A military officer and three policemen were gunned down in Egypt’s Sinai Peninsula on Wednesday, according to a local security source.
Gunmen stopped a private car in the North Sinai city of Beer al-Abd and opened fire on its occupants, killing them on the spot, the source said on condition of anonymity because he was unauthorised to speak to media.
No group has yet claimed responsibility for the attack and Egyptian authorities have yet to comment.
The Sinai Peninsula has remained the epicentre of a deadly militant insurgency since mid-2013, when the military deposed Mohamed Morsi, Egypt’s first freely-elected president, in a military coup.
Hundreds of Egyptian security personnel have been since killed in attacks across the volatile region, particularly in northeastern Sinai that shares borders with Israel and the blockaded Gaza Strip.
Egyptian authorities say they are battling the Welayat Sinai, or Province of Sinai group, which is said to have links to the Daesh terror organisation.
