Paris (CNN) Witnesses have reported gunfire amid a police raid in the northern Paris suburb of Saint-Denis as authorities hunt for two suspects from Friday's deadly terrorist attacks who are believed to be at large. 
 
 Police blocked off roads early Wednesday in Saint-Denis, which is home to the Stade de France sports stadium where three suicide bombings took place Friday. 
 
 CNN affiliate BFMTV reported that police officers have been wounded by gunfire during a raid seeking one of the suspects in the wave of violence across Paris , which killed at least 129 people and wounded hundreds more. 
 
 French police wouldn't comment on whether any officers had been shot in the Saint-Denis operation. 
 
 BFMTV reported that the police raid was linked to the hunt for the so-called "ninth suspect," who may appear in a video recorded by a witness to the attacks. 
 
 Police have been analyzing the video, which shows two gunmen inside a black car linked to the attacks and perhaps a third individual driving the car, French media reported. 
 
 Seven of the attackers were killed during the wave of violence Friday night, and an international arrest warrant is already out for one suspect, Salah Abdeslam , a 26-year-old Frenchman. The identity of the possible ninth suspect is unknown. 
 
 Brother urges suspect to surrender 
 
 Abdeslam's older brother has urged the suspect, who was last seen driving toward the Belgian border hours after the attacks, to turn himself over to authorities. 
 
 "I would tell him to surrender. That's the best solution," Mohamed Abdeslam told CNN's Erin Burnett on Tuesday. "But of course, if he has something to do with it, he must accept responsibility."

 In their push to unravel the attack plot and the suspected network behind it, counterterrorism and intelligence officials say investigators have uncovered a clue that could be a big break: cell phones believed to belong to the attackers. 
 
 According to the officials, one of the phones contained a message, sent sometime before the attacks began, to the effect of: OK, we're ready. 
 
 "It points to a sort of organization," CNN terrorism analyst Paul Cruickshank said, "an attempt to try to synchronize what was going down." 
 
 But cracking into their communication won't be easy. 
 
 Investigators have found encrypted apps on the phones, which appear to have left no trace of messages or any indication of who would have been receiving them, according to officials briefed on the French investigation. 
 
 'These are not regular people' 
 
 Mohamed Abdeslam said the last time he saw his brothers was about a week ago. 
 
 "They left without saying goodbye," he said. 
 
 Now one of them is a wanted fugitive. And authorities say another Abdeslam brother, Ibrahim, 31, was among the seven terrorists who either killed themselves or were killed by police in a series of coordinated attacks across the French capital on Friday night that killed at least 129 people and wounded hundreds more.

 Mohamed Abdeslam told CNN that before the attacks, he'd noticed his brothers changing and adopting more radical views. He suspects the Internet could have played a role. But he said his family was shocked by the attack, and had no idea what they were planning. 
 
 "My brother who participated in this terrorist act must have been psychologically ready to commit such an act. These are not regular people," he said. "You cannot have the slightest doubt that they have been prepared, that they must not leave any trace which would cause suspicion that they might do such things. And even if you saw them every day, their behavior was quite normal." 
 
 Suspects questioned by Belgian authorities in February 
 
 Police stopped Salah Abdeslam hours after the attacks in a car on his way toward the Belgian border. They let him go because he apparently hadn't yet been linked to the terrorist operation. 
 
 Both he and Ibrahim were previously known to authorities: Belgian prosecutor Eric Van Der Sypt told CNN's Ivan Watson that police questioned the Abdeslam brothers in February.

 "Ibrahim tried to go to Syria and was sent back by the Turks in the beginning of 2015," Van Der Sypt said. "It was after that that we questioned him." 
 
 Both brothers were released, the federal prosecutor said, after they denied wanting to go to Syria. 
 
 He said Belgian authorities were also trying to keep an eye on Bilal Hadfi, one of the suicide bombers who struck outside the Stade de France, according to several sources. "We knew (Hadfi) was in Syria," Van Der Sypt said. "But what we didn't know is apparently he was back, as he blew himself up in Paris. But we had no knowledge of the fact that he was back in Europe." 
 
 'At war' and launching airstrikes 
 
 Declaring the country is "at war," French President Francois Hollande has proposed extending the state of emergency for a further three months, along with sweeping new anti-terrorism laws. 
 
 Security forces conducted more than 128 new raids around the country overnight, Interior Minister Bernard Cazeneuve said Tuesday during a radio interview.

 Tracking the suspected mastermind 
 
 Before the Paris attacks, France and its allies had tried to target a prominent ISIS member who is believed to have planned the assault on the French capital, a French source close to the investigation said.

 Western intelligence agencies had attempted to track Abdelhamid Abaaoud , a Belgian citizen thought to be in Syria, but they weren't able to locate him, the source told CNN on Tuesday. 
 
 Abaaoud had been implicated in the planning of a number of terrorist attacks and conspiracies in Western Europe before the Paris attacks. 

 PARIS (AP) — France made an unprecedented demand for its European Union allies to support its military action against the Islamic State group as it launched new airstrikes on the militants' Syrian stronghold, days after attacks in Paris linked to the group killed at least 129 people.

 France invoked a never-before-used article of the EU's Lisbon Treaty obliging members of the 28-nation bloc to give "aid and assistance by all the means in their power" to a member country that is "the victim of armed aggression on its territory." 
 
 French Defense Minister Jean-Yves Le Drian said EU partners could help "either by taking part in France's operations in Syria or Iraq, or by easing the load or providing support for France in other operations." 
 
 French military spokesman Col. Gilles Jaron said the latest airstrikes in the Islamic State group's de-facto capital of Raqqa destroyed a command post and training camp. On Monday, President Francois Hollande vowed to forge a united coalition capable of defeating the jihadists at home and abroad. 
 
 The Paris attacks on Friday, claimed by IS, have galvanized international determination to confront the militants. 
 
 Hollande has said the victims came from at least 19 nations, and the international community, led by the U.S. and Russia, must overcome their deep-seated divisions over Syria to destroy IS on its home turf. 
 
 U.S. Secretary of State John Kerry flew to France as a gesture of solidarity and met Hollande and Foreign Minister Laurent Fabius on Tuesday. 
 
 Standing with Hollande at the Elysee Palace, Kerry said the carnage in the French capital on Friday, along with recent attacks in Egypt, Lebanon and Turkey, made it clear that more pressure must be brought to bear on the Islamic extremists. 
 
 Kerry said, "we have to step up our efforts to hit them at the core where they're planning these things and also obviously to do more on borders in terms the movement of people." 
 
 Earlier, he told U.S. Embassy staff Friday's attacks were an assault on civilization and common decency. 
 
 "This is just raw terror," he said, vowing that the campaign against IS will succeed. "We will end the scourge of Daesh," he said, referring to the group by its Arabic acronym. 
 
 Addressing lawmakers Monday after France observed a minute's silence to honor the dead and the 350 wounded, Hollande said "Friday's acts of war were decided and planned in Syria." 
 
 "They were organized in Belgium and perpetrated on our soil with French complicity with one specific goal: to sow fear and to divide us," Hollande told parliament in a rare joint session convened at the Palace of Versailles. 
 
 Hollande said Syria has become "the biggest factory of terrorism the world has ever known and the international community is still too divided and too incoherent." 
 
 French and other Western intelligence agencies face an urgent challenge to track down the surviving members of the three Islamic State units who inflicted the unprecedented bloodshed in France and, perhaps more importantly, to target their distant commanders in IS-controlled parts of Syria. 
 
 A French security official said anti-terror intelligence officials had identified Abdelhamid Abaaoud, a Belgian of Moroccan descent, as chief architect of the attacks on a rock concert, a soccer game and popular nightspots in one of Paris' trendiest districts. 
 
 The official cited chatter from IS figures that Abaaoud had recommended a concert as an ideal target for inflicting maximum casualties, as well as electronic communications between Abaaoud and one of the Paris attackers who blew himself up. 
 
 The official spoke on condition of anonymity to discuss the sensitive investigation. 
 
 Abaaoud came to public attention last year by boasting in an IS propaganda video about his pride in piling the dead bodies of "infidel" enemies into a trailer. Anti-terror agencies previously linked him to a series of abortive shooting plots this year in Belgium and France, including a planned attack on a passenger train that was thwarted by American passengers who overpowered the lone gunman. 
 
 French police have used emergency powers to conduct almost 300 searches since Sunday night that netted 127 arrests and 31 weapons. 
 
 Interior Minister Bernard Cazeneuve said Tuesday that police carried out 128 police raids overnight, as he conceded that "the majority of those who were involved in this attack were unknown to our services." 
 
 Police have seized a Kalashnikov assault rifle, three automatic pistols and a bulletproof vest from a suspected arms dealer with jihadist sympathies, and a rocket launcher and other military-grade gear from his parents' home. 
 
 But police have yet to announce the capture of anyone suspected of direct involvement in Friday's slaughter. Seven attackers died — six after detonating suicide belts and a seventh from police gunfire — but Iraqi intelligence officials told The Associated Press that its sources indicated 19 participated in the attack and five others provided hands-on logistical support.

 France has mobilised 115,000 security personnel in the wake of Friday's Paris attacks by Islamist militants, Interior Minister Bernard Cazeneuve has said. 
 
 Mr Cazeneuve said 128 more raids on suspected militants were carried out. French air strikes also hit Islamic State in Syria overnight. 
 
 IS has said it carried out the attacks on bars, restaurants, a concert hall and a stadium in which 129 people died. 
 
 A huge manhunt is under way for one of the suspects, Salah Abdeslam. 
 
 He is believed to have fled across the border to his native Belgium. Belgian police have released more pictures of the wanted man. 
 
 Follow the latest live updates 
 
 Belgium's government has raised its terror threat level because of the failure so far to arrest Abdeslam. Tuesday's football match between the national team and Spain has been cancelled as a result. 
 
 Mr Cazeneuve said: "We have mobilised 115,000 police, gendarmes and military over the whole of our national territory to insure the protection of French people." 
 
 The interior minister added that 128 raids on suspected Islamist militants had been carried out overnight on Monday to Tuesday. More than 160 raids were made earlier on Monday, with 23 people arrested and dozens of weapons seized.

 French media reported that during raids police found a safe house used by the attackers in Bobigny, a suburb of Paris. Abdeslam's brother Brahim, who died in the attacks, is thought to have rented it. 
 
 A property in another suburb, Alfortville, has also been identified as being used by the attackers, and a car is being investigated, media said.

 German media reported three arrests near Aachen, on the Belgian border, in an operation linked to the attacks. 
 
 Meanwhile France has invoked a previously unused clause in the Treaty on European Union obliging other member states to provide it with "aid and assistance by all means in their power". 
 
 Within minutes, EU foreign policy chief Federica Mogherini said that all 28 member states had agreed. 
 
 "Today France asked the European Union for aid and assistance. And today the whole of Europe replied in unison: 'Yes'." she tweeted (in French).

 The attacks in Paris - which also left more than 400 people wounded, some critically - have galvanised Western countries in their campaign against the so-called Islamic State. 
 
 UK Chancellor George Osborne said in a speech that IS was trying to develop the ability to launch deadly cyber-attacks on the UK. 
 
 President Hollande's proposals 
 
 Extension of state of emergency by three months 
 
 Changes to the constitution to allow the government to revoke citizenship of any convicted terrorists of dual nationality. Currently only those born outside France and naturalised can lose their citizenship 
 
 Measures to speed up expulsion of foreign nationals considered a threat to public order 
 
 Budget increases and extra recruitment to security forces and judiciary 
 
 During a visit to the GCHQ listening station in Cheltenham, he announced that the UK's investment in fighting cybercrime would double. 
 
 President Hollande told a rare joint session of the French parliament on Monday that he would table a bill to extend for three months the state of emergency declared after the attacks. Parliament will vote on the measure on Wednesday. 
 
 According to Prime Minister Manuel Valls, intelligence services have files on 10,500 individuals who have been radicalised to a greater or lesser extent.

 What is Islamic State? 
 
 IS is a notoriously violent Islamist group which controls large parts of Syria and Iraq. It has declared its territory a caliphate - a state governed in accordance with Islamic law - under its leader Abu Bakr al-Baghdadi. 
 
 What does it want? 
 
 IS demands allegiance from all Muslims, rejects national borders and seeks to expand its territory. It follows its own extreme version of Sunni Islam and regards non-believers as deserving of death. 
 
 How strong is IS? 
 
 IS projects a powerful image, partly through propaganda and sheer brutality, and is the world's richest insurgent group. It has about 30,000 fighters but is facing daily bombing by a US-led multi-national coalition, which has vowed to destroy it.

 A look at Abdelhamid Abaaoud, the 27-year-old Belgian citizen suspected of having helped plan the Paris terror attacks, and who is believed to have masterminded failed attacks on a high-speed train and a church. Mark Kelly reports. 
 
 An Islamic State operative suspected of helping plan the Paris attacks had been monitored in Syria by Western allies seeking to kill him in an airstrike, but they couldn’t locate him in the weeks before the plot was carried out, two Western security officials said. 
 
 The operative, a Belgian citizen named Abdelhamid Abaaoud, was convicted in absentia in Brussels earlier this year of recruiting jihadists, was suspected of masterminding a foiled plot to behead police officers, escaped to Syria and was profiled in Islamic State’s...
– "France is at war," President Francois Hollande declared on Monday, and an army has been mobilized: The BBC reports that 115,000 security personnel, including police and troops, have been deployed across the country in the aftermath of the Paris attacks. More than 150 raids were carried out across France on Monday, and Interior Minister Bernard Cazeneuve announced on Tuesday that another 128 anti-terror raids were carried out overnight, as French warplanes struck the ISIS "capital" of Raqqa for a second night, reports CNN. In other developments: France's fight is now the fight of the entire European Union, under a treaty the country has invoked. The clause, which calls for all 28 states to offer "aid and assistance by all means in their power" after "armed aggression" on a member's territory, has never been used before, the BBC reports. Hollande is seeking to amend France's laws and constitution to make anti-terror operations easier to conduct, the New York Times reports. He has signaled that he wants to expand surveillance powers, as well as give police more power to conduct raids without a warrant. He also plans to extend the current state of emergency for three months and make it possible to strip dual nationals convicted of terror offenses of their French passports. Authorities in France and Belgium are still hunting Salah Abdeslam, a Belgian national believed to have helped the Paris attackers. Abdelhamid Abaaoud, another Belgian national, is suspected of masterminding the attack. Security sources tell the Wall Street Journal that he is believed to be in Syria, where Western forces have been trying for weeks or months to find him and kill him with an airstrike. The identity of an attacker found dead at the Stade de France with a Syrian passport bearing the name Ahmad al Mohammad nearby is still a mystery, the Guardian reports. Police in Serbia have arrested a man carrying a passport with the same details, and they believe both passports are fake. The attacker is believed to have entered Greece last month posing as a refugee, and more than 20 states now say they will refuse Syrian refugees because they fear there could be terrorists among them. John Kerry met Hollande in Paris on Tuesday and called for greater cooperation against ISIS after attacks that he has described as an assault on civilization, reports the AP. "We have to step up our efforts to hit them at the core where they're planning these things and also obviously to do more on borders in terms [of] the movement of people," he said.
