Updated at 1:47 p.m. ET: Amid fresh bloodshed in the Syrian city of Homs, the U.N. Security Council on Saturday failed to pass a resolution calling on the Syrian president to step down.

Russia and China vetoed?the resolution?endorsing an Arab League call for Bashar Assad to leave power. The other 13 council members, including the U.S., France and Britain, voted in favor of the resolution.

The vote took place as Syrian forces pummeled the city of Homs with mortar and artillery fire that activists say killed more than 200 people in one of the bloodiest episodes of the uprising against Assad's regime. The U.N. says more than 5,400 people have been killed over almost 11 months in a Syrian government crackdown on civilian protests.

"The United States is disgusted that a couple of members of this Council continue to prevent us from fulfilling our sole purpose here -- addressing an ever-deepening crisis in Syria and a growing threat to regional peace and security," said Susan Rice, the U.S. ambassador to the U.N.

"This is a great disappointment to the people of Syria and the Middle East, and to all supporters of democracy and human rights," a spokesperson for U.N. Secretary-General Ban Ki-moon said. "It undermines the role of the United Nations and the international community in this period when the Syrian authorities must hear a unified voice calling for an immediate end to its violence against the Syrian people."

U.S. Secretary of State Hillary Clinton said it had not been possible to work constructively with Russia ahead of the vote. "I thought that there might be some ways to bridge, even at this last moment, a few of the concerns that the Russians had. I offered to work in a constructive manner to do so. That has not been possible,'' she told reporters at a security conference in Munich.

Syria has been a key Russian ally since Soviet times and Moscow has opposed any U.N. call that could be interpreted as advocating military intervention or regime change.

Earlier, President Barack Obama issued a statement calling the latest attack on Homs "an unspeakable assault" by Assad's regime.

"Assad must halt his campaign of killing and crimes against his own people now. He must step aside and allow a democratic transition to proceed immediately," Obama said.

"The Syrian regime's policy of maintaining power by terrorizing its people only indicates its inherent weakness and inevitable collapse," Obama said. "Assad has no right to lead Syria, and has lost all legitimacy with his people and the internationalcommunity."

The violence in Homs sparked protests in several cities outside Syria.

British police used batons and riot shields to try to hold back protesters trying to storm the Syrian Embassy in London.?"We want to close the embassy!" demonstrators shouted.

Police brought in sandbags and riot gear to regain control of the surging crowd, which lobbed objects at the embassy, situated near Buckingham Palace.
