Ibrahim survived the bombing near his Cairo home but some 20 policemen and civilians were wounded. The death sentences can be appealed. Known locally as the "Ansar Beit al-Maqdis", after the militant outfit he led in the restive Sinai region, Ashmawy later broke with the group after it pledged allegiance to the Islamic State group in November 2014.
He was already sentenced to death in November by a military court over his role in 14 attacks including the 2014 killing of 22 soldiers at a border post with Libya. Other charges against him included forming an Al-Qaeda aligned militant group in Libya.
