Syria conflict: Ceasefire pressure grows over peace plan

The UN Security Council has urged Syria to implement "urgently and visibly" a peace plan requiring a 10 April deadline for ending a military offensive against the opposition.

Envoy Kofi Annan's plan calls for Damascus to pull back troops and heavy weaponry by that date, and for a full ceasefire by 48 hours later.

UN Secretary General Ban Ki-moon said the conflict was getting worse and urged both sides to seize the moment and end the violence.
