Security officials say unidentified assailants have killed two policemen and wounded another two when they opened fire on their patrol in northern Sinai.
The officials said the shooting happened early Wednesday when the gunmen opened fire on a two-vehicle police patrol in the Egyptian city of Arish.
The officials spoke on condition of anonymity because they were not authorized to speak to the media.
Security has for months been tenuous in northern Sinai, with Bedouins involved in human trafficking to Israel challenging the local police.
Attempts by authorities to bring the area under government control are being met with resistance from the heavily armed Bedouins.
