Syria regime keeps up Aleppo assault after truce failure

Regime forces and their allies were advancing street by street in the eastern sector which has been out of government hands since 2012.

"Clashes on the ground as well as fierce airstrikes went on all night and are continuing Sunday, especially in the Sheikh Said district" of eastern Aleppo, said Rami Abdel Rahman, head of the Syrian Observatory for Human Rights.

It said regime forces took control of the Jandul crossroads in the northeast of the city.

The latest advances aim to clear the way for "a crucial and decisive land offensive", said the Damascus daily Al-Watan which is close to the government.

The army launched its assault on the besieged sector of Aleppo more than two weeks ago with the backing of Russian airstrikes, aiming to reunite the city which was Syria's economic hub before its conflict erupted in 2011.

According to the Observatory, airstrikes by the regime and its Russian ally have claimed 273 lives, mostly civilians and including 53 children, since the September 22 launch of operations to reunite the government-held west and the east of Aleppo.

Another 17 civilians have died in artillery bombardment of eastern districts, says the Britain-based monitoring group.

The Observatory, which compiles its information from sources on the ground, said 50 civilians, including nine children, have also died in rebel bombardment of regime-controlled western districts.

On Saturday at the United Nations, Russia vetoed a French-drafted resolution demanding an end to the bombing of Aleppo, but its own rival measure on a truce was rejected.

The failure of the two resolutions deepened divisions at the UN Security Council between Moscow and the Western powers backing rebel forces in Syria's five-year war which has killed 300,000 people.

France's draft called for an end to all military flights over Aleppo and to air strikes on the rebel-held east that has 250,000 inhabitants.

It was the fifth time that Russia used its veto to block UN action on the war in Syria.

Shortly after Russia's veto, the Security Council rejected a rival draft presented by Moscow that called for a ceasefire but did not mention a halt in airstrikes.

Britain's ambassador to the United Nations, Matthew Rycroft, described Saturday's failure in New York as "a bad day for Russia, but an even worse day for the people of Aleppo".

Following the meeting, his Russian counterpart Vitaly Churkin insisted that diplomatic efforts on Syria were not dead.

The assault on Aleppo was launched just days after the collapse of a ceasefire in Syria that was brokered jointly by Russia and the United States.

German Foreign Minister Frank-Walter Steinmeier warned that the mounting tensions between Washington and Moscow over the Syrian conflict had created a situation "more dangerous" than the Cold War.
