Rockets and missiles from Gaza killed four civilians in Israel, while Israeli strikes killed 19 Palestinians, more than half of them civilians, in surging cross-border fighting on Sunday, according to Gazan officials and the Israeli military. Israeli Prime Minister Benjamin Netanyahu said he ordered the military to continue "massive strikes" against Gaza's ruling Hamas group and Islamic Jihad in the most serious border clashes since a spate of fighting in November. Israel's military said that more than 600 rockets and other projectiles - over 150 of them intercepted by its Iron Dome anti-missile system - had been fired at southern Israeli cities and villages since Friday. It said it attacked more than 260 targets belonging to Gaza militant groups. Gaza officials said Israeli air strikes and artillery fire killed 27 people, including 14 civilians, since Friday.
