The UN secretary-general has deplored the use of chemical weapons in Syria and has called on the international community to sanction those responsible for the chemical attacks. Ban Ki-moon\'s statement came a day after a UN report concluded that banned chemical weapons were used at least five times before Damascus agreed to dismantle its arsenal. However, the report did not lay blame for the attacks. The report said evidence indicated chemical weapons were probably used in Khan al-Assal outside Aleppo on March 19 against soldiers and civilians. The government and opposition accused each other of using chemical weapons at Khan al-Assal, and the report said none of the parties in Syria denied their use in the village. Swedish expert Ake Sellstrom, who led the UN investigation team that compiled the report, reminded reporters that the mandate did not allow him to point the finger at anyone. Show Less >>
