Turkey's refugee camps full to capacity with Syrians fleeing bloodshed Mr Assad's jet fighters have carried out air strikes near the two camps inside Syria. Mr Simpson stressed how Turkey was risking the safety of the refugees by preventing them from crossing the border. "If a bomb lands and it's too late, then Turkey would have a lot of questions to answer," he said. If the refugees are still waiting inside Syria when winter comes, their living conditions would inevitably worsen, warned Mr Simpson. Fierce fighting took place in three areas of Aleppo on Monday as government forces and rebels struggled for control of Syria's commercial capital. The Ummayyad Mosque, dating from the 13th century, was severely damaged. But Lakhdar Brahimi, the United Nations and Arab League peace envoy, proposed a ceasefire to coincide with the Muslim holiday of Eid al-Adha, which falls on Oct 25. After a visit to Tehran, Mr Brahimi asked Iran to help deliver the agreement of Mr Assad, its close ally. Any ceasefire would be a first step towards allowing a "political process to develop," he added. However, Mr Brahimi's predecessor, Kofi Annan, the former UN secretary general, made similar suggestions without reducing the bloodshed. Separately, an Armenian passenger aircraft bound for Syria landed in Turkey yesterday to allow its cargo to be inspected. The plane was allowed to continue its journey after Turkey confirmed that it was carrying humanitarian aid. Turkey has announced that it will not allow its airspace to be used for the transfer of weapons to Syria's regime.
