The latest on the aftermath of a coordinated militant assault on Egyptian security forces in the restive northern Sinai that killed dozens of troops and set off the bloodiest fighting in the peninsula in decades (all times local).

Egyptian security officials say gunmen shot and killed a security guard in front of a bank in Fayoum, 80 kilometers (50 miles) southwest of Cairo.

It was not immediately clear if Thursday's shooting was a criminal or militant attack. The officials spoke on condition of anonymity because they were not authorized to brief media.

It came a day after Islamic State-linked extremists swarmed military positions in the northern Sinai, setting off battles that killed dozens of troops and some 100 militants.

Also, on Wednesday, Egyptian security forces killed nine members of the outlawed Muslim Brotherhood, including a former lawmaker, in a raid on a Cairo residence. Egyptian officials said the forces were fired upon, while the Brotherhood said the men were "murdered in cold blood" and called for a rebellion.

A newspaper close to the Egyptian government says the Islamic State-linked militants who attacked troops in the Sinai Peninsula used sophisticated weaponry, including Russian-made Kornet anti-tank missiles.

In a graphic on its front page Thursday, el-Watan daily says the attackers also used mortars, anti-aircraft guns and other guided missiles.

The attack, which included a wave of suicide bombings and assaults on security installations by dozens of militants, was Sinai's deadliest fighting in decades. Security officials said dozens of troops were killed, along with some 100 attackers.

Newspapers led their front pages with the attack, with many describing it as a "war." Graphic photographs released by the military showed the bodies of extremists killed in the fighting who were wearing combat fatigues.
