Heavy air strikes and clashes shook the Syrian rebel enclave of Eastern Ghouta on Tuesday, as France and Britain called for an emergency UN Security Council meeting on the escalating violence, the Daily Mail reported.
Eight hundred civilians -- including at least 177 children -- have been killed since Russia-backed regime forces launched an assault on the besieged enclave outside Damascus on February 18, the Syrian Observatory for Human Rights said in its latest death toll.
Russia suffered its own heavy losses on Tuesday as the defence ministry said a Russian transport plane crashlanded at an airbase in western Syria, killing all 32 people on board.
Bombardment and clashes in Eastern Ghouta, the last major rebel stronghold near Damascus have persisted despite a month-long ceasefire demanded by the Security Council more than a week ago.
At least 19 civilians were killed on Tuesday, according to the Syrian Observatory, a Britain-based monitor.
