Britain says the United Nations Security Council is "going to take action immediately now" to draw up a council resolution for a U.N.-administered cease fire enforcement mechanism in Syria.

That follows Saturday's meeting in Vienna at which foreign ministers of nearly 20 countries agreed to an ambitious but incomplete plan for bringing peace to the country. They agreed on a way to enforce a cease-fire and set a Jan. 1 deadline for the start of negotiations between President Bashar Assad's government and opposition groups.

Britain currently holds the council presidency. Deputy Ambassador Peter Wilson told reporters Monday that the council is "very clear" that it will act right away on putting a resolution together.

Wilson did not give details, including how long the process would take.
