Armed Palestinians in wetsuits and flippers emerged from the Mediterranean and fired toward a beachfront Israeli settlement in the Gaza Strip. Two attackers were killed, and a third was wounded and fled. The Islamic militant group Hamas claimed responsibility for the attack on the Tel Katifa settlement in Gaza. In a farewell video, two attackers posed in their wetsuits, with oxygen tanks strapped to their backs and goggles pulled above their foreheads. The settlement attack is the first of "earthshaking operations to come," a Hamas leaflet said.
