Egyptian officials say suspected militants have ambushed a police convoy in the Sinai Peninsula, killing two policemen and wounding two others, including a police brigadier-general.

The police and military officials say the Monday attack began with the detonation of roadside bombs that destroyed and set ablaze three armored vehicles and a fourth one carrying signal jamming equipment. The suspected militants later opened fire with machine guns.

The attack took place about 30 kilometers (20 miles) west of el-Arish in northern Sinai, the epicenter of a long-running insurgency by militants now led by the extremist Islamic State group.

The officials spoke on condition of anonymity because they were not authorized to speak to the media.
