A bomb exploded in the Cairo district of Nasr City, an Islamist stronghold, narrowly missing Interior Minister Ibrahim shortly after he left his home; 22 people were injured by the blast, including 10 police officers and a child. After the attack, in which gunmen also strafed his vehicle, Ibrahim warned of more terrorist attacks; Islamists have increasingly called for violence in the wake of the government’s crackdown on the Muslim Brotherhood. A security force said the government will start establishing a buffer zone between Egypt and the Gaza Strip; the first phase will start south of the Rafah crossing.
