Gunmen attack university in Kenya
Masked gunmen have stormed a university campus in Garissa Town in eastern Kenya.
Police official Musa Yego said gunshots and explosions can be heard from a building on the campus, which is surrounded by police and military.
It was not immediately clear if there were any deaths or injuries.
Kenya's northern and eastern regions, which border Somalia, have been most affected by attacks blamed on al Qaida-linked al-Shabab Islamists from Somalia.
They have vowed retribution against Kenya for sending its troops to Somalia.
