- Al-Shabab gunmen storm Kenyan university
- At least 70 dead and 79 injured
- Unknown number of hostages seized
- 500 students rescued
- Garissa university, 150km from Somali border, sealed off
The BBC's Thomas Amter has just sent this photo of emergency workers in Garissa.
The Kenyan government say this is the man behind the Garissa University College attack:
They've put a $215,000 (£145,000) reward for his capture.
Mohamed Kuno has several aliases but is best known as Mohamed Dulyadin, which means ambidextrous in the Somali language.BBC News looks at how he rose up the ranks of al-Shabab.
BBC Somali analyst Abdullahi Abdi has been speaking to residents of Garissa. They have been telling him the attack is similar to the 2013 Westgate shopping mall siege, and it shows the government has not learnt anything. Residents are also wondering why there were only two guards on duty when the militants stormed the university, despite warnings of an attack.
The gunmen in Garissa in Kenya have been isolated by the security forcesin the female dormitories:
Here's a map of the scene of the siege:

Body bags are being brought into a plane. It's a very dramatic scene considering it is about 15 hours since the start of the attack at Garissa University College.

This is the phone call that changed Nigeria:
President Goodluck Jonathan is congratulating Gen Muhammadu Buhari on winning the country's election.
But the call almost didn't happen. The editor of the BBC Hausa serviceMansur Liman says Mr Jonathan couldn't get through to Gen Buhari so he sent a messenger round to his house to tell him to pick up his phone.
What started as a largely Somali movement has become a regional one, with growing numbers of Kenyan recruits. Al-Shabab has recently released propaganda videos aimed at a Kenyan audience. There are also unconfirmed reports that it is considering switching allegiance to Islamic State in order to remain relevant.
This is hurting tourism. Just last week, the UK's Foreign Office updated its travel advice, warning British citizens against all but essential travel to eastern Kenya and most of the coast.
Al-Shabab says it attacked Garissa University College because it is at war with Kenya. In October 2011, Kenyan troops entered Somalia in an effort to stop the Islamists from crossing the long, porous border between the two countries and kidnapping people. But their presence achieved the opposite effect, provoking al-Shabab to increase its activity in Kenya.
Al-Shabab killed 67 people when its heavily armed fighters attacked the Westgate shopping centre in the Kenyan capital, Nairobi, a year-and-a-half ago. Originally based in Somalia, it has killed dozens more since then in its pursuit of a hardline Islamic law.

Here's anothertweet from the Kenya National Disaster Operation Centre on the latest in Garissa: "9 critically injured from the #GarissaAttack have been airlifted from Garissa Airbase to Nairobi for treatment."
Soldiers are pictured in position around the perimeter wall of Garissa University College.
Some patients who were airlifted from Garissa have now arrived for treatment as Kenyatta National Hospital in the capital, Nairobi.
The head of the African Union mission in Somalia says he has been "shaken" by the attack in Garissa.
"If you attack a military, it's an equal battle, but if you go after students, who are learning, who are preparing for the future of Africa, it's different. Al-Shabab has no accountability... Because of who they have targeted today - I'm a father myself - I am shaken,"Maman Sidikou told BBC Focus On Africa's James Copnall.
Morocco have won their appeal against their bans from the 2017 and 2019 Africa Cup of Nations tournaments. The Court of Arbitration for Sport has overturned the ruling which was made by the Confederation of African Football after Morocco did not host the 2015 finals.
The BBC's Bashkas Jugsooda'ay will be live onFocus on Africa at 15:00 GMT with the latest from Garissa and the ongoing siege as the programme tries to establish how many students have been taken hostage at the university campus.
A memorial service for Ugandan prosecutor Joan Kagezi, who was shot dead on Monday evening, has taken place in the capital, Kampala. The church was packed with family, friends and government officials. Ms Kagezi was killed by gunmen on a motorbike in a suburb of Kampala on the eve of the trial of 13 men accused of taking part in the 2010 bombings by al-Shabab in Kampala. She was also handling cases on the killing of Muslim clerics.
We've got more details on the man the Kenyan government calls the mastermind of the Garissa University College attack.
A BBC Somali Service reporter says that Mohamed Kuno was a headmaster at a madrassa, or Islamic school, in Garissa before he quit in 2007 to join the now-defunct Union of Islamic Courts (UIC) Somalia.
When the UIC split, Mr Kuno joined al-Shabab and became a high-ranking official. Recently he has been involved in running al-Shabab's activities in Kenya. He goes by the nickname "Dulyadeyn", which in Somali means the long-armed one.
The Kenya government has named Mohamed Kuno as the mastermind of the Garissa University College attack.
Kenya's Cabinet Secretary for Internal Security Joseph Nkaiserry placed a $53,000 (£35,700) bounty on Mr Kuno.
Elsewhere in Africa, Sierra Leone, Liberia and Guinea area still dealing with the Ebola outbreak - and you can ask questions about the safest way to bury people killed by the illness later today.
Red Cross's Amanda McClelland will be on theBBC Ebola Facebook page from 1600-1700 GMT.
The charity carried out more than 15,000 burials in the three West African states during the current outbreak.

President Kenyatta also said that he had ordered the head of police to "ensure that the 10,000 recruits whose enrolment is pending, promptly report for training at the Kenya Police College".
"We have suffered unnecessarily due to shortage of security personnel. Kenya badly needs additional officers, and I will not keep the nation waiting."
Kenya's President Uhuru Kenyattahas just released a statement about the siege, saying "terrorists attacked Garissa University College killed and wounded several people and have taken others hostage".
He extended his condolences "to the families of those who have perished" and said the government had undertaken the "appropriate deployment".
"I also urge Kenyans to stay calm as we resolve this matter, and to provide the authorities with any information they may have in connection with any threats to our security."
Kenyan-based journalist Hannah McNeish has just spoken to Abdikadir Sugow, the spokesman for Garissa's governor.
Shetweets that he says the "militia are still on top of the roof. They're gathering there." Mr Sugow said they want to have an "aerial view" of security forces below and there is intermittent gunfire.
From witness statements it is not clear whether the attackers are wearing "protective clothing" or "suicide vests", Mr Sugow said.
Kenyan journalist Dennis Okari, who is at the site of the Garissa University College,tweets: "The gunmen are holed up inside the upper hostel section. I can hear gunfire from the other end @ntvkenya".
BBC Africa, en route to Garissa
There have been several recent al-Shabab attacks in north-eastern Kenya - and as in the Westgate mall siege of 2013 - Muslims and non-Muslims have been separated.
A survivor of a bus that was attacked in Novembertold the BBC that the militants asked passengers to recite from the Koran - those who could not quote from the Muslim religious text were killed.
When al-Shabab called the BBC earlier, its spokesman said the group was behind the attack on Garissa University College because it considers it a non-Muslim institution on Muslim ground.
