Angela Kane, Ban Ki-moon's Under Secretary General, has been sent to Damascus to negotiate with Syrian authorities to allow the United Nations access to investigate yesterday's alleged chemical attack.
Angela Kane previously negotiated with the regime for greater access for UN inspectors, earlier in the conflict.
In a statement, the UN said:
The Secretary-General believed that the incidents reported yesterday need to be investigated without delay.
The Secretary-General now calls for the Mission, presently in Damascus, to be granted permission and access to swiftly investigate the incident which occurred on the morning of August 21, 2013.
A formal request is being sent by the United Nations to the Government of Syria in this regard. He expects to receive a positive response without delay.
