Russia opposes Syria sanctions after UN gas attacks probe

United Nations: Russia dismissed as "unconvincing" the findings of a UN-led investigation showing that Syrian forces had carried out three chemical attacks, and said no sanctions should be imposed.

"We believe that the proof is not there for any punitive action to be taken. It's simply not there," Russian Ambassador Vitaly Churkin told reporters following a closed-door Security Council meeting yesterday.

A joint United Nations-Organisation for the Prohibition of Chemical Weapons (OPCW) panel concluded that government forces carried out three chlorine gas attacks on villages in 2014 and 2015.

It was the first time an international probe blamed President Bashar al-Assad's forces after years of denial from Damascus.

But Churkin told the council that the findings were not strong enough to trigger sanctions.

The conclusions "in most cases... Are not substantiated by sufficient testimonial basis, first of all material proof, they are full of contradictions and therefore unconvincing," he said, according of a text of his remarks.

The findings are "not definitive, have no legally binding force and cannot serve as accusatory conclusions for taking legal decisions," he added.

Britain and France pressed demands for sanctions, arguing that UN resolutions provided for such action in response to the use of chemical weapons.

"Those responsible for using chemical weapons must be sanctioned. There is no other way," French Ambassador Francois Delattre told reporters.

"There should be accountability for every single person involved in any use of chemical weapons in Syria or indeed anywhere else," British Ambassador Matthew Rycroft said.

Government helicopters flying from two regime-controlled air bases dropped chlorine barrel-bombs on the villages of Qmenas, Talmenes and Sarmin, in rebel-held Idlib province, the panel's latest report said.

Chlorine use as a weapon is banned under the Chemical Weapons Convention, which Syria joined in 2013 under pressure from Russia, Assad's ally.

Although previous OPCW reports concluded that toxic gases were used as weapons in Syria's five-year war, they stopped short of identifying the perpetrators.

The panel identified the 253 and 255 squadrons of the 63rd helicopter brigade, which flew from the Hama and Humaymim air bases, and the 628 squadron based in Humaymim as the perpetrators.

The UN-OPCW panel also found that the Islamic State group used mustard gas as a weapon in August 2015.

"We stand firmly behind the report and its conclusions," Virginia Gamba, who led the investigative panel, told reporters.

Russia also rejected a US proposal to extend the panel's mandate - which ends on Monday - for a year, arguing that more time is needed to discuss the experts' future work.
