CAIRO (AP) — The Egyptian military said Wednesday that three officers were killed in the last week in the restive northern Sinai Peninsula, where it is battling an Islamic State-led insurgency.

Another two troops were wounded, Col. Tamer el-Rifai, a military spokesman, said in a statement posted on Facebook. The troops killed 30 militants and arrested at least 173 suspects, he said, adding that airstrikes in the Western Desert destroyed 10 vehicles laden with weapons and ammunition.

The military said troops dismantled more than 74 explosive devices. It said that troops also destroyed more than 430 hideouts, munition and weapons depots and targeted more than 40 illegal opium fields in the past week.

The figures provided by the military could not be independently confirmed as media access to the northern Sinai is heavily restricted.
