Russia will use its veto to block a draft UN resolution imposing sanctions on the Assad regime for the use of chemical weapons, the deputy ambassador said Friday."There is an argument that the resolution itself contradicts the fundamental principle of presumption of innocence before the investigation is over," Vladimir Safronkov told reporters following a closed-door meeting of the Security Council.There is "tremendous pressure" on the U.N.-Organization for the Prohibition of Chemical Weapons (OPCW) joint inquiry into the use of chemical weapons in Syria to produce a one-sided result, he told reporters."I just explained our position very clearly to our partners. If it is tabled we will veto it," Safronkov said of the resolution.Russia is the largest international backer of the Syrian regime of Bashar Assad."How much longer is Russia going to continue to babysit and make excuses for the Syrian regime?" U.S. Ambassador to the U.N. Nikki Haley said later.She told reporters that after an "overwhelming" vote to investigate whether Syria was using chemical weapons, "the results have come out and people don't like what the results are. It is ridiculous."The draft resolution seeks to blacklist 11 military commanders and officials of the Syrian regime, and 10 government and related entities involved in the development and production of chemical weapons.It calls for an asset freeze and travel ban for the individuals and entities across all U.N. member states.On Thursday, two diplomats told Reuters the resolution could be put up for a vote as early as next week.UK Ambassador to the U.N. Peter Wilson said on Friday it would be put to a vote as soon as possible.Earlier, the head of the French mission to the U.N. said the credibility of the Security Council was at stake over the issue."What is at stake here frankly is the credibility of the Security Council," he told reporters.The U.N.-OPCW inquiry found that Syrian regime forces were responsible for three chlorine gas attacks and that Daesh militants had used mustard gas, according to reports seen by Reuters last year.Assad's regime has denied its forces have used chemical weapons.The discussions coincide with talks between representatives of the Assad regime and the opposition with U.N. mediator Staffan de Mistura which started on Thursday in Geneva.The nearly six-year-long conflict in Syria has killed at least 300,000 people and displaced millions, according to groups that monitor the war.
