Security forces defused Saturday a bomb near a bus station in Giza’s Boulaq Al-Dakrour district, reported Al-Ahram Arabic website.

Police received notification that a passerby reported seeing a strange object in Masraf Street in front of a bus station. Security personnel were sent to inspect it and found it was a hand grenade.

Egypt witnessed two explosions last month. The largest one targeted the security directorate building in the Nile Delta city of Mansoura, killing 16 people and injuring more than 135. A smaller explosion in eastern Cairo near a bus injured five.

The interior ministry in statements held the Muslim Brotherhood — from which ousted president Mohamed Morsi hails — responsible for the recent attacks though the Islamist group repeatedly denied involvement.

Egypt witnessed Friday some of the worst violent clashes between supporters of the Muslim Brotherhood and the police in months. Egypt's Ministry of Health said Saturday that 14 people were killed and 62 injured in clashes across the country.

Some 17 police officers were also injured, according to a senior security source.
