Russia, US clash at UN over escalation in Syria fighting

Russia and the United States clashed at the United Nations on Tuesday, accusing each other of supporting terrorism, during a Security Council meeting convened over a sudden escalation of fighting in Syria.

Syrian rebels captured Aleppo last week in an attack initiated by Hayat Tahrir al-Sham. Formerly known as the Nusra Front, it was al Qaeda's official wing in Syria until breaking ties in 2016. It is sanctioned by the UN Security Council.

Deputy US Ambassador to the UN Robert Wood called for a de-escalation of the fighting in Syria and the protection of civilians. He also expressed concern that the rebel offensive was led by Hayat Tahrir al-Sham.

"The fact that HTS is listed as a terrorist organization by the US and UN does not justify the further atrocities by the Assad regime and its Russian backers," said Wood, accusing Syrian President Bashar al-Assad's forces and Russia of causing civilian casualties in attacks on schools and hospitals.

In remarks directed at Wood, Russia's UN Ambassador Vassily Nebenzia said, "You were unable to summon the courage to condemn a clear terrorist attack undertaken against peaceful civilians in peaceful Syrian cities.

"There are no illusions that Washington will ever be willing to sincerely combat international terrorism," he said.

"To be frank we are pleased that we are on opposite sides of the barricades right now from you."

Wood responded by accusing Nebenzia of being in "no position to lecture us on this issue" because Moscow "props up regimes that sponsor terrorism around the world".

"The United States has for decades fought the scourge of terrorism and will continue to fight that scourge of terrorism," he said.
