Egyptian military sources announced Sunday a commando brigade carried out an anti-terror military crackdown in the Sinai Peninsula, leaving nine terrorists killed and six others arrested, Al-Bawaba News reported. The crackdown, which targeted terrorist bastions in the North Sinai villages of Tumma, Lafattat and Al-Gura, wholly devastated six vehicles and 18 motorbikes used by terrorists for bombing purposes, the sources added. Egypt has launched a severe military crackdown against terrorists in the restive Sinai following a string of deadly terrorist attacks claiming hundreds of lives among security personnel and civilians. Terrorist bombings have largely increased across Egypt since former president Mohamed Morsi was ousted July 2013 amid military-backed mass street protests. The Egyptian military started November 2014 the construction of a buffer zone on the eastern border with the Islamist-run Gaza Strip in a bid to thwart smuggling weapons and militants into the volatile peninsula.
