Israeli Prime Minister Benjamin Netanyahu declared on Monday that Israel’s fierce offensive against Hamas in the Gaza Strip has “only begun.”

Netanyahu delivered the pronouncement in a nationally televised address as Israel pressed ahead with a third day of heavy airstrikes in Gaza following Hamas’ unprecedented and deadly incursion into Israel.

“We’re in a war for existence. A war that we will win,” Netanyahu said. “This war has been put upon us by evil people, animals who celebrate murder of people. … We always knew who Hamas was, and now the rest of the world does, too. Hamas is ISIS, a despicable enemy who wanted a war, and they’ll get a war.”
