The Ansar Beit al-Maqdes jihadist group has claimed responsibility for the attempted assassination of Interior Minister Mohamed Ibrahim last Thursday. The group published pictures of the bomb exploding and promised to publish a video of the operation.
In a statement on Sunday evening, the group said that one of its members carried out "Operation Martyrdom" in order to avenge the massacres of the Republican Guard, Rabaa al-Adaweya, Ramses and Alexandria.
The group urged citizens to stay away from defense and interior ministry installations to be out of harm's way.
