Egypt’s military said on Tuesday it has killed more than 40 extremists in a wide-ranging campaign in the Sinai Peninsula where ISIS has been waging a deadly insurgency.

The announcement came a day after seven civilians were killed in a foiled attack on a checkpoint with an explosives-laden car.

An army tank had intercepted the vehicle and driven over it, almost flattening it, before the explosives went off, according to a video released by the army.

ISIS has waged deadly attacks on the military and police, most recently on a checkpoint in Sinai on July 7 that killed at least 21 soldiers.

But the military, which killed the leader of the group's affiliate in Egypt last year, says it is closing in on the extremists.

It said in a statement on Tuesday that “40 extremists” have been killed in the week-long campaign against the militants.

A military source told AFP that soldiers were staying put in locations they cleared of the militants, rather than withdrawing as in past campaigns.

“After storming terrorist hideouts, the soldiers are staying there,” the source, who requested anonymity, told AFP.

“The terrorist elements are fleeing and leaving their weapons behind,” he added.

Extremists launched an insurgency in Sinai after the military overthrew the divisive Islamist president Mohamed Morsi in 2013.

They have maintained a steady war of attrition with sniper attacks and roadside bombings.

But unlike their parent organization in Iraq and Syria, they have been unable to seize population centers in the peninsula bordering Israel and Gaza.
