Israeli soldiers mourn during the funeral for their fallen comrade Natan Cohen, killed during fighting in Gaza on Tuesday, in the town of Modi'in, between Jerusalem and Tel Aviv
Israeli soldiers mourn during the funeral for their fallen comrade Natan Cohen, killed during fighting in Gaza on Tuesday, in the town of Modi'in, between Jerusalem and Tel Aviv 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.

Rebel commander Alexander Khodakovsky of the Vostok Battalion speaks during an interview in Donetsk in this July 8, 2014 file photo. A powerful Ukrainian rebel leader has confirmed that pro-Russian separatists had anti-aircraft missiles of the type Washington says were used to shoot down Malaysia Airlines flight MH17. In an interview with Reuters, Khodakovsky, commander of the Vostok Battalion, acknowledged for the first time since the airliner was brought down in eastern Ukraine on Thursday that the rebels did possess the BUK missile system. He also indicated that the BUK may have originated in Russia and could have been sent back to remove proof of its presence.
