No end in sight for Syria conflict, envoy warns The veteran troubleshooter, who took over as envoy from former UN secretary general Kofi Annan on September 1, also appealed to the divided 15-nation Security Council for united backing for his efforts. The Syrian war has divided the Security Council, where Russia and China have already wielded their veto powers three times to resist international action demanded by Western and many Arab states. President Barack Obama was to lead Western demands for action on Syria at the start of the UN General Assembly on Tuesday. Mr Obama will be one of the opening speakers at the annual meeting of world leaders where the Syria conflict, mounting fears of a military strike on Iran and anti-West protests in Muslim nations are set to dominate. UN leader Ban Ki-moon, France's President Francois Hollande and Qatar's emir, Sheikh Hamad bin Khalifa Al-Thani, a key backer of the Syrian opposition, are also expected to lambast Assad on the opening morning. Fighting raged across the country again on Monday, killing at least another 60 people - 27 civilians, 22 soldiers and 11 rebels, according to the Syrian Observatory for Human Rights. The rebels have captured hundreds of kilometres (miles) of territory in the country's north in the past six months, an AFP correspondent who visited the area in March reported. "The army is unable to control the ground, so it tries to stay in power by dominating the skies," the Observatory's Rami Abdel Rahman said. The latest lethal air attack killed five people, including three children from the same family, when warplanes struck in Aleppo, the commercial hub where troops and rebels have been locked in fierce fighting since mid-July. Videos posted to YouTube by activists, which AFP was unable to authenticate immediately, showed a mountain of rubble and men trying to clear away slabs of debris to free trapped residents. A girl was killed in heavy shelling of Aleppo's northern neighbourhood of Sheikh Maqsud where several homes were destroyed, while another died in shelling in Aleppo province, the Britain-based Observatory said. And a five-year old child was killed by gunfire in the town of Dael, in the southern province of Daraa, where the revolt against Assad's rule erupted in March 2011, while the seventh child died in shelling on the central town of Quseir. The Observatory said at least 2,000 children have been killed in the Syrian conflict. "Children should be going back to school, but instead they are suffering extreme violence," Abdel Rahman said. This would not be possible were the international community not silenced by its paralysis. British-based charity Save the Children said it has collected "shocking testimony" revealing that "children have been the targets of brutal attacks, seen the deaths of parents, siblings and other children, and have witnessed and experienced torture." Released on Tuesday, "Untold Atrocities," a collection of first-hand accounts of the conflict from Syrian children and parents after fleeing their country, contains graphic details of how children have been caught up in Syria's war. The spark that lit Syria's revolt was the arrest and torture in March 2011 of a group of boys in the southern town of Daraa, after they daubed walls with anti-regime graffiti. Opposition groups tolerated by the Damascus regime have meanwhile called on both the military and rebels to stop the violence immediately, at the end of a meeting in the Syrian capital on Sunday. The group also urged Brahimi to organise an international conference of all concerned parties to push for a democratic transition in the country. Syria's main opposition coalition issued a statement on Monday, guaranteeing no revenge attacks would be carried out against the country's minority Alawite sect, to which Assad belongs. At least 29,000 people have been killed since the revolt erupted last year, according to the Observatory, while the United Nations puts the toll at more than 20,000.
