U.S. Secretary of State John Kerry looks back before his flight leaving Paris March 31, 2014. Kerry broke from his travel schedule for the second time in a week to rush back to the Middle East on Monday to try to salvage Israeli-Palestinian peace talks. The U.S.-brokered negotiations faced a crisis at the weekend when Israel, saying it was seeking a Palestinian commitment to continue negotiations beyond an end-April deadline, failed to press ahead with a promised release of Palestinian prisoners.
