Kenya police kill 3 suspected jihadists after warning of al-Shabab dressing up as officers

A police report dated Tuesday says officers found ammonium nitrate, weapons and ammunition including more than 1,600 bullets and military and police uniforms at a house in Likoni on the East African country's coast.

An internal police circular seen by The Associated Press and dated Sept. 23 warns officers in the coastal region to "treat with suspicion" government and United Nations-branded vehicles as intelligence shows that the al-Shabab extremist group, based in neighboring Somalia, was planning attacks on key installations and social places.
