A local official says twin grenade blasts have injured four people in a northern Kenyan town.
North Eastern Province Police Commissioner James Seriani says one grenade was thrown into the staff canteen at the prison in the town of Garissa late on Thursday. The other explosion happened simultaneously at a local hotel.
The attacks are the most recent in a string of grenade and bomb blasts since Kenya sent troops into Somalia two months ago.
Kenya says it wants to break the al-Qaeda linked Somali insurgency, which it blames for a series of attacks on Kenyan soil. - Sapa-AP
