The Egyptian military conducted airstrikes against Islamic State affiliate hideouts in the Egyptian desert Saturday in response to Friday's attack on a Sufi mosque in the Sinai province which killed 305 people, 27 of them children.
The attack, committed by extremists who reportedly carried an ISIS flag, is the deadliest such incident in Egypt's recent history. ISIS has not publicly claimed responsibility.
Egyptian President Abdel Fattah el-Sisi had promised to retaliate with "brute force," and the bombing reportedly targeted the attackers' vehicles. Cairo did not give details on the number or location of the air raids.
