Masked gunmen shot and killed two police sergeants in Arish, North Sinai, on Wednesday, a security source has said.
The assailants shot the men in the head and chest as they were walking to work on a street in central Arish.
The Sinai peninsula had seen recurrent deadly attacks against army and police troops since the ouster of former president Mohamed Morsi in 2013. Most of the attacks have been claimed by Islamic State affiliate, the Sinai Province.
