Cairo — A bomb exploded outside a military intelligence building northeast of Egypt's capital on Sunday, wounding four people, state-run Nile TV reported.
Security officials said remains of a vehicle were found nearby the building in Anshas, a village in Sharqiya province that houses a number of military facilities, and they are looking into whether the blast was a car bomb.
Military spokesman Ahmed Mohammed Ali said on his official Facebook page that the explosion damaged the back wall of the military intelligence office and wounded four soldiers guarding it. He said an investigation had begun to determine what caused the blast.
Initial reports suggested that explosion was caused by a hand grenade thrown at the building.
No one has claimed responsibility for the attack.
