The Israeli community of Netiv Haasara is seen in front of flares fired by the Israeli army in Gaza July 23, 2014. Gaza fighting raged on Wednesday, displacing thousands more Palestinians in the battered territory as U.S. Secretary of State John Kerry said efforts to secure a truce between Israel and Hamas had made some progress. Israel launched its offensive on July 8 to halt rocket salvoes by Hamas and its allies, which have struggled under an Israeli-Egyptian economic blockade on Gaza and angered by a crackdown on their supporters in the nearby occupied West Bank.
