Prime Minister Benjamin Netanyahu on Thursday stressed that the international community should not try to strengthen either Iran or Islamic State against the other."We have to weaken both of them and prevent attacks and armament of them both," the premier said at an event at the national cyber park in Beersheba. "I say to you, stand in opposition to these dark forces that suppress human rights and murder people and hang them in town squares."In light of Wednesday's deadly attacks by Islamic State-linked militant in the Sinai Peninsula, the premier added that Israel now faces the threat of Islamic State affiliates on its northern and southern borders. While listing the group formerly known as ISIS as one of the region's main threats, he said that the radical group's activities are "nothing compared to the capabilities being built by the Iranian regime."
