The UN Security Council has drawn up a draft resolution on sending 300 international monitors to Syria after considering two versions.
A Russian draft would see observers sent immediately, but Britain, France and Germany want to wait until Syria has withdrawn troops and weaponry from population centres.
A handful of observers are already in Syria, monitoring the fragile ceasefire.
The Security Council will meet to vote on a resolution later today.
Although overall violence has fallen, countless ceasefire violations have already been reported by activists and reporters on the ground.
According to international reports, at least 23 people were killed yesterday, 10 of them in a roadside bomb targeting security forces, and most of the others in army shelling on the city of Homs.
