IS claims responsibility for car bombing

Extremist group says attack on state security building was reprisal for execution of 6

Islamic State's Egyptian affiliate said it was behind a car bombing that wounded 29 people near a state security building and courthouse in a Cairo suburb early on Thursday.

A statement circulated on Twitter by supporters of the group, Sinai province, said the bomb was a reprisal for the execution of six of its members convicted of carrying out an attack north of the Egyptian capital last year.
