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 in decades.

The army said 17 troops and 90 militants were killed, but security officials and media reports said dozens of soldiers and some 100 militants died in the fighting.

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.
