AL ARISH, Egypt: A pair of attacks by suspected militants on Saturday killed four policemen and injured six others in the turbulent north of Egypt’s Sinai Peninsula, according to security officials, bringing to 16 the number of policemen and soldiers known to have been slain in the area in three days.

They said three policemen were killed when their armoured vehicle hit a roadside bomb south of Sinai’s coastal city of Al Arish. Six more policemen were injured in that attack.

Later on Saturday, a policeman manning a checkpoint also south of Al Arish was killed by a sniper’s bullet, they said.

The officials spoke on condition of anonymity because they were not authorised to brief reporters.

The attacks came two days after Sinai militants killed 10 army soldiers and two policemen in Sinai.

Northern Sinai, which borders Israel and the Gaza Strip, has long been home to an insurgency by militants, now led by a local affiliate of the Daesh group. Attacks by militants grew deadlier and more frequent after the 2013 ouster of an Islamist president whose one year in office proved divisive.
