Egypt’s interior ministry said the police foiled a bomb attack in a busy area in Giza on Friday.

Explosives experts defused a home-made bomb that aimed to target a security checkpoint near El-Istiqama mosque in Giza on the outskirts of Greater Cairo, the ministry said in a statement.

A security official told Ahram Online that two improvised bombs were thrown from a bridge at members of a security checpoint in the area. One civilian was injured by shrapnel, he added.

A video circulating online showed a blast in a cordoned-off area under a bridge, with security officials, police vehicles and an ambulance in the vicinity.

Al-Ahram Arabic news website published photos from the site showing smashed glass on the street, a shattered car window and a damaged apartment building door.

The ministry blamed “members of the terrorist Muslim Brotherhood group” for the attack.

No group has yet claimed responsibility for the attack.

Egypt designated the Brotherhood a terrorist organisation in late 2013, months following the ouster of its Islamist president Mohamed Morsi after mass protests against his rule.

Military and police forces have been pressing ahead with an extensive campaign to eradicate Islamist militants over the past year, which is mainly focused in the border Sinai region.
