New York, Dhu-AlHijjah 22, 1437, September 23, 2016, SPA -- The United States and Russia failed to agree on how to revive a short-lived ceasefire in Syria during the meeting of the International Syria Support Group on the sidelines of the annual United Nations gathering of world leaders in New York. "We have exchanged ideas with the Russians and we plan to consult tomorrow" on their ideas, U.S. Secretary of State John Kerry said after the meeting. "I am no less determined today than I was yesterday but I am even more frustrated." Russia and the United States agreed on Sept. 9 a deal aimed at putting Syria's peace process back on track. It included a nationwide truce, improved humanitarian aid access and the possibility of joint military targeting of banned ISIS groups. Kerry demanded on Wednesday that Russia and the Syrian government immediately halt flights over Syrian battle zones. -- SPA 03:46 LOCAL TIME 00:46 GMT www.spa.gov.sa/w
