UN Security Council diplomats were locked in tough negotiations on Friday on a draft resolution demanding a 30-day ceasefire in Syria.
A vote initially scheduled for 1600 GMT was pushed back to 1930 GMT, but by 4:00 pm (2100 GMT), there was no indication of a new time for council action.
Negotiations went into high gear to avoid a Russian veto of the text, which would establish a truce to allow humanitarian aid deliveries and medical evacuations.
