In April 2014, and again in June, Netanyahu spoke of his deep concerns when Hamas and the Palestinian Authority agreed and then formed a unity government, and was severely critical of both the United States and European governments' decision to work with the Palestinian coalition government. He blamed Hamas for the kidnapping and murder of three Israeli teenagers in June 2014, and launched a massive search and arrest operation on the West Bank, targeting members of Hamas in particular, and over the following weeks hit 60 targets in Gaza. Missile and rocket exchanges between Gaza militants and the IDF escalated after the bodies of the teenagers, who had been killed almost immediately as the government had good reasons to suspect, were discovered on 30 June 2014. After several Hamas operatives were killed, either in an explosion or from an Israeli bombing, Hamas officially declared it would launch rockets from Gaza into Israel, and Israel started Operation Protective Edge in the Gaza Strip, formally ending the November 2012 ceasefire agreement. The prime minister did a round of television shows in the United States and described Hamas as "genocidal terrorists" in an interview on CNN. When asked if Gazan casualties from the operation might spark "a third intifada", Netanyahu replied that Hamas was working towards that goal.
