Cairo - Gunmen have killed a top Egyptian army officer outside his home on Friday in the northern Sinai where the local affiliate of the Islamic State group is leading an insurrection, the army spokesman said.
"Three terrorist elements fired on Brigadier General Hisham Mohammed Mahmud, one of the heroes of the armed forces, outside his home in El-Arish after prayers, resulting in his martyrdom," the spokesman said on Facebook.
The army has been battling an Islamist insurgency in northern Sinai which escalated after the military overthrew Islamist president Mohamed Morsi in 2013.
Egypt's government says hundreds of police and soldiers have died in the attacks, which have also hit Cairo and the Nile Delta.
Most of the attacks have been claimed by the Egyptian IS affiliate, which also said it bombed a Russian plane over Sinai in October 2015 killing all 224 people on board, most of them Russian tourists.
