China and Russia veto UN resolution on Syria
China and Russia have vetoed a UN Security Council resolution backing calls for Syria's President Bashr-al Assad to stand down.
The two permanent members of the council rejected the draft resolution despite strong condemnation by US President Barack Obama of the violence.
The vote came just hours after activists accused the Syrian security forces of carrying out one of the bloodiest attacks since the uprising began, killing at least 55 people in the city of Homs.
President Obama has accused the Syrian government of murdering civilians in what he is calling an "unspeakable assault" in the city of Homs.
He has demanded that President Assad step down.
It is being claimed up to 350 people were killed by his forces last night.
Meanwhile, hundreds of people are holding a protest outside the Syrian embassy in London.
The building is being pelted with bottles as police try to hold the demonstrators back.
