Gunmen have stormed a Kenyan university killing at least 14 people and taking hostages, aid workers and police say.
An unconfirmed number were wounded after attackers stormed a university in Garissa town. Troops have surrounded the campus and are engaging the gunmen.
Militant Islamist group al-Shabab said it carried out the attack.
Muslim and non-Muslim hostages had been separated, and 15 of the Muslim had been freed, said a spokesman for the group, which is part of al-Qaeda.
The militants, who have their headquarters in neighbouring Somalia, have regularly targeted Kenya.
About five masked gunmen are said to have stormed the university.
A policeman at the scene told Reuters news agency that some students had been taken hostage.

Security forces were now trying to flush out the gunmen, a police statement posted on Twitter said.
It urged people to stay away from the area. The statement did not confirm that hostages had been taken.
Two guards were confirmed killed at the main university gate, with two policemen and a student among the injured. But eyewitnesses spoke of many casualties inside the building.
