Airstrikes and rocket fire hit the Syrian opposition enclave of eastern Ghouta for a seventh straight day on Saturday after the United Nations again delayed a vote on a ceasefire.

The Assad regime launched a devastating bombardment of the enclave just outside capital Damascus last Sunday that has now killed at least 500 civilians in seven days, 121 of them children, according to the Syrian Observatory for Human Rights.

Deadly new strikes hit the enclave as the U.N. Security Council prepared to vote on a ceasefire resolution, while more bodies were recovered from the rubble from previous raids, the monitor said.

The Britain-based monitor of the war previously said three civilians were killed and 12 wounded in Russian airstrikes on the eastern Ghouta town of Harasta early Saturday.

Moscow, which intervened militarily in support of its Damascus ally in 2015, has denied any direct involvement in the eastern Ghouta bombardment.

The Observatory relies on a network of sources inside Syria and says it determines whose planes carry out raids according to type, location, flight patterns and munitions used.

U.S. President Donald Trump on Friday said Russia's recent actions in Syria were a "disgrace."
