AMMAN/GENEVA (Reuters) - Washington and Moscow said on Monday they were working hard to extend a truce in Syria to Aleppo, the divided northern city where a sharp escalation of violence in recent weeks has left a ceasefire in tatters and torpedoed peace talks.

U.S. Secretary of State Joahn Kerry was in Geneva for meetings with other dignitaries to try to revive the two-month-old U.S. and Russia-sponsored cessation of hostilities, which quieted guns for the first time during the five-year Syrian war but which has unravelled in recent days.
