The Russian Foreign Ministry said on Sunday a draft French UN Security Council resolution on Syria would have helped Islamist militants in the Aleppo area by protecting them from aerial bombing.
In a statement, the ministry also said the French text was politicized and one-sided.
Russia on Saturday vetoed the resolution, which demanded an end to air strikes on Aleppo and military over flights.
"An explicit attempt was made, by banning flights in the Aleppo area, to provide cover for the terrorists of Jabhat Al-Nusra and associated militants," the ministry said.
