- The UK ambassador says Russia abused its veto power
- A counterresolution by Russia failed to get the votes to pass
The British ambassador to the United Nations, Matthew Rycroft, accused Russia of abusing its veto power.
"In the end, no resolution of this Security Council can end this war. The only thing that can end this war is a change of policy in Moscow," he said after the veto.
A separate counterresolution by Russia that did not call for a halt in airstrikes on Aleppo failed to get the necessary votes to pass.
"It was one weird day" at the Council, Russian Ambassador Vitaly Churkin said after the failed vote and his veto. He called it a "strange spectacle."
The Russian veto had been expected as Russia and the United States have been fighting over Russia's support of the Assad regime.
Friday, US Secretary of State John Kerry said airstrikes by Syrian troops with Russian support should be investigated as war crimes as they hit hospitals and civilians.
