In 1985, Air India Flight 182 flying from Canada was blown up by a bomb while in Irish airspace, killing 329 people, including 280 Canadian citizens, mostly of Indian birth or descent, and 22 Indians. The incident was the deadliest act of air terrorism before 9/11, and the first bombing of a 747 Jumbo Jet which would set a pattern for future air terrorism plots. The crash occurred within an hour of the fatal Narita Airport Bombing which also originated from Canada without the passenger for the bag that exploded on the ground. Evidence from the explosions, witnesses and wiretaps of militants pointed to an attempt to actually blow up two airliners simultaneously by members of the Babbar Khalsa Khalistan movement militant group based in Canada to punish India for attacking the Golden Temple. The Iranian Embassy siege took place in 1980, after a group of six armed men stormed the Iranian embassy in South Kensington, London. The government ordered the Special Air Service (SAS), a special forces regiment of the British Army, to conduct an assault—Operation Nimrod—to rescue the remaining hostages. This response set the tone for how Western governments would respond to terrorism. Replacing an era of negotiation with one of military intervention. Chechen separatists, led by Shamil Basayev, carried out several attacks on Russian targets between 1994 and 2006. In the June 1995 Budyonnovsk hospital hostage crisis, Basayev-led separatists took over 1,000 civilians hostage in a hospital in the southern Russian city of Budyonnovsk. When Russian special forces attempted to free the hostages, 105 civilians and 25 Russian troops were killed. Major events - most deadly (300 deaths or more) or most covered - after the 2001 September 11 attacks include the 2002 Moscow Theatre Siege, the 2003 Istanbul bombings, the 2004 Madrid train bombings, the 2004 Beslan school hostage crisis, the 2005 London bombings, the 2005 New Delhi bombings, the 2007 Yazidi communities bombings, the 2008 Mumbai Hotel Siege, the 2009 Makombo massacre, the 2011 Norway attacks, the 2013 Iraq attacks, the 2014 Camp Speicher massacre, the 2014 Gamboru Ngala attack, the 2015 Paris attacks, the 2016 Karrada bombing, the 2016 Mosul massacre, the 2016 Hamam al-Alil massacre, the 2017 Mogadishu bombings and the 2017 Sinai attack. In the 21st century, most victims of terrorist attacks have been killed in Iraq, Afghanistan, Nigeria, Syria, Pakistan, India, Somalia or Yemen. The Moscow theatre hostage crisis was the seizure of a crowded Moscow theatre on 23 October 2002 by some 40 to 50 armed Chechens who claimed allegiance to the Islamist militant separatist movement in Chechnya.
