At least six people were wounded in a car bombing near a state security building and courthouse in a Cairo suburb early this morning.

The sources, who inspected the site of the blast in Shubra al-Khaima, said there was a burned-out vehicle and crater. 

A witness said he saw a man park a vehicle that exploded after he stepped away from it.

Militants based in the Sinai, who support the Islamic State group that controls parts ofIraq and Syria and have a presence in Egypt's neighbor Libya, have previously claimed responsibility for attacks on security forces.

Hundreds of soldiers and police have been killed since the army toppled Islamist President Mohamed Mursi in 2013 after mass protests against his rule.
