US Secretary of State John Kerry plays with his crutches as he talks to reporters before leaving for Vienna, Austria, at Andrews Air Force Base in Washington Friday. Kerry will join negotiators from six powers and Iran to seek an agreement under which Tehran would curb its nuclear program in exchange for relief from economic sanctions that have crippled its economy. Kerry said he was hopeful about nuclear negotiations with Iran, but that he did not wish to convey optimism ahead of a June 30th deadline for a deal. |
