Kofi Annan is describing the Syrian government's acceptance of his plan as "important initial step."
But he adds implementation is key.
"I had a six-point plan which the Security Council has endorsed, dealing with issues of political discussions, withdrawal of heavy weapons and troops and populations centres; humanitarian assistance being allowed in unimpeded; release of prisoners; freedom of movement, and access for journalists to go in and out, so we will need to see how we move ahead and implement this agreement that they have accepted."
Annan's plan has been on the table for two weeks now, and has garnered wide support after being unanimously endorsed by the UN Security Council last week.
