Damascus: Russian President Vladimir Putin said on Saturday he remained "more positive than negative" over a shaky ceasefire in Syria, but a senior rebel in Aleppo warned the truce "will not hold out" as some fighting persisted and aid failed to come through.

The ceasefire is the result of an agreement between Russia, which backs Syrian President Bashar al-Assad with air power, and the United States, which supports some rebel groups, and has cooled fighting since coming into effect last Monday.
