CAIRO (AP) — An Egyptian militant group claimed responsibility for bomb blasts outside the presidential palace in Cairo that killed two senior police officers and wounded 10 other people, taunting authorities that it was able to strike even the most secure locations in a campaign of violence against police and the military.

The attack outside the Ittihadiya palace, where newly elected President Abdel-Fattah el-Sissi holds office, raised alarm among officials Tuesday over the security breach. Militants were able to carry out the attack despite multiple closed-circuit security cameras in the area and warnings from the militant group that it planted bombs at the palace.
