The council is expected to meet on Wednesday to discuss the air strikes and clashes in the Syrian enclave of Eastern Ghouta that have continued despite a ceasefire demanded by the top UN body ten days ago.
Backed by Russia, the council unanimously adopted on February 24 a resolution demanding the 30-day cessation of hostilities to allow deliveries of humanitarian aid and evacuations of the sick and wounded.
A first aid convoy reached Eastern Ghouta on Monday but the operation was cut short as air strikes pounded the enclave, killing at least 68 civilians, according to a human rights monitor.
Air strikes, and artillery and rocket fire on the last major rebel-held enclave near the capital Damascus have killed hundreds and devastated residential areas since they began on February 18.
