Annan: The killing must stop

Former United Nations secretary general and joint UN-Arab League envoy on Syria Kofi Annan says the international community must unite in condemnation of the regime's behaviour:

"Let me say one thing, if we are going to succeed it is extremely important that we all accept there should be one process of mediation – the one that the UN and the Arab League have asked me to lead,"

"The message is clear, which is that the killing and violence must stop, humanitarian agencies must be given access to do their work. But it is regrettable that it is not happening."

"I would plead with him [Assad] that he should engage, not only with me but with the process we are launching."
