Kenya's Garissa University College stormed by gunmen
Masked gunmen have stormed a university near the Somali border in north-eastern Kenya, killing at least two people and injuring about 30, the BBC reported.
Troops have surrounded Garissa University College and are engaging the attackers.
Witnesses spoke of the gunmen firing indiscriminately and there are fears the casualty toll could rise.
It is not clear who is behind the attack, but Somali al-Shabab militants have regularly targeted Kenya.
Garissa and other border areas have been regularly attacked.
Some five masked gunmen are said to have stormed the university. There are reports that hostages have been taken.
Kenyan police said the gunmen shot guards at the main gate at about 05:30 local time (02:30 GMT).
Nearby policemen then engaged in a fierce exchange of fire and the gunmen escaped into the university buildings.
Security forces were now trying to "flush them out," a police statement said. It urged people to stay away from the area.
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.
The gunmen reportedly ordered students to lie down on the floor, but at least 27 are known to have escaped and are at a military facility.
