MANDERA, Kenya, March 2 (Xinhua) -- Five Kenyan police officers were killed early Friday after suspected Al-Shabaab militants attacked two camps in Mandera County, northeast Kenya.

Northeastern Regional Commissioner Mohamud Saleh confirmed to Xinhua by phone that the two attacks targeted administration police and Kenya police camps in Lafey town.

Saleh said the dead included four administration police officers and a national police reservist.

He said the terrorists are suspected to have crossed the border from neighboring Somalia, destroyed a telecommunication mast in the area to cut off communication and later stormed the two police camps.

According to security sources, the heavily armed militia numbered about 100. Three other police officers were injured in the confrontation.
