Three Egyptian policemen were injured late Saturday in a shooting attack in Giza province, west of Cairo, a security source said Sunday.

"Unidentified militants opened fire on a police checkpoint in Giza city, leaving three policemen wounded," the source told The Anadolu Agency, requesting anonymity.

The attackers fled the scene immediately after the assault, he added.

No group has yet claimed responsibility for the attack, the latest in a series of assaults that have mainly targeted security forces since last year's ouster of president Mohamed Morsi by the army in 2013.

Two militant groups – "Ansar Beit al-Maqdis," which is largely active in the Sinai Peninsula, and "Agnad Misr" – have claimed responsibility for some of the attacks.
