Gaza militants fired rockets and Israel carried out air strikes in a cross-border exchange on Thursday, after 11 Palestinians were killed a day earlier during an Israeli raid in the occupied West Bank, renewing concerns of a broader escalation. Israel’s military said six rockets had been fired from Gaza overnight, setting off air raid sirens in southern Israeli communities. Five rockets were intercepted by missile defences and the other fell in an open area. No injuries were reported. Watch this video for more.
