CAIRO, April 14 (Xinhua) -- Egyptian security forces killed 27 militants in the Sinai Peninsula in the latest raids as part of the anti-terror military operation "Sinai 2018," a military spokesman said Saturday.

Six militants were killed in airstrikes on their hideouts, while 12 others died in a shootout with security forces, the spokesman said in a statement.

It did not disclose where and how the nine other militants were killed.

As many as 114 suspects were arrested in the raids, according to the statement.

The army found and destroyed a training camp, which included a shooting range, an obstacle course and an underground conference room.

It also seized a large quantity of ammunition and telecommunication equipment, as well as 15 vehicles, and destroyed 43 motorcycles.

More than 190 militants and at least 22 soldiers have been killed in the massive operation launched on Feb. 9.

Egypt's North Sinai Province has been the center of terrorist attacks, which have killed hundreds of policemen and soldiers since the military ouster of former Islamist President Mohamed Morsi in July 2013.

Most of the terror attacks were carried out by a Sinai-based group affiliated with the Islamic State (IS) regional terrorist group.
