Militants from an ISIS affiliate ambushed a convoy of cement trucks late Thursday from an army factory in the central Sinai Peninsula, killing eight civilian employees and two soldiers, security officials said.

Lt. Col. Ibrahim Hussein Mohammed was killed in the nighttime attack near the town of Nakhl, the officials added. The militants, from the group formerly known as Ansar Beit al-Maqdis, stole the men's weapons and burnt seven trucks.

The officials spoke on condition of anonymity because they were not authorized to talk to reporters. ISIS did not immediately claim responsibility for the attack.

Egypt is also facing a growing number of attacks by militants in its Western Desert, the latest of which killed 16 policemen according to an official tally issued by the Interior Ministry. Security officials, however, have told journalists that dozens more, including high-ranking counterterrorism officers, perished in the Oct. 20 attack some 135 kilometers (84 miles) southwest of the capital, Cairo.
