The UN General Assembly has demanded an immediate ceasefire in Syria and urgent aid deliveries in a resolution adopted by a strong majority as Syrian forces launched another assault on Aleppo. <br/><br/>The measure drafted by Canada passed by a vote of 122 to<br/>13 in the 193-nation assembly yesterday, with 36 abstentions. Russia, Iran and China opposed the resolution.'<br/><br/>Lebanon, Iraq, South Africa, Nigeria and India were among the countries that abstained from the vote on the non-binding text. The vote came as Syrian President Bashar al-Assad's forces carried out more air raids on Aleppo and the United Nations reported that hundreds of men had gone missing after fleeing the battered city.<br/><br/>Russian Ambassador Vitaly Churkin accused the United<br/>States of engaging in aggressive rhetoric and argued that the resolution had major shortcomings by failing to emphasize the need to combat terrorist groups. <br/><br/>Russia and China this week vetoed a draft Security Council resolution calling for a seven-day ceasefire in Aleppo, the Syrian city that is on the verge of falling to government forces. It was the sixth time that Moscow, a close Assad ally, has used its veto in the council to block action over Syria.
