CRI听力:Kenya Carnage: Government Official's Son 'A Gunman'

One of the gunmen who are said to have carried out last week's attack at Garrissa University in Kenya has been identified as the son of a government official.

Abdirahim Abdullahi is the son of a local chief in the north-east of the country.

It's believed he joined al-Shabaab in Somalia in 2013.

Last week's attack at Garissa University left 148 people dead and 79 others injured.

Four of the attackers killed themselves after being surrounded.

A fifth gunman is under arrest.

The harrowing ordeal included hundreds of young people being taken hostage.

"Because we were not thinking. We just ran. What we could see was just getting out of that place and exiting that place. So we just ran to the fence, jumped the fence then go out of the school. All we could do was just run. No one was looking back, no one wanted to see what was happening. Because everybody was running for their lives."

Kenyan President Uhuru Kenyatta is vowing a response in "the severest way possible."

Kenya has been a target of al-Shabaab since the country's armed forces began leading an African Union mission into neighboring Somalia in 2011.
