"The OPCW’s Fact-Finding Mission does not attribute responsibility for an attack. Unfortunately, Russia has vetoed the renewal of Joint Investigative Mechanism, which was the only impartial and independent body with the mandate for attributing responsibility, at the UN Security Council five times," the statement said.
On April 10, the UN Security Council failed to adopt either of the two Russian-drafted resolutions or the one drafted by the United States which were calling for an investigation into the reported chemical attack — the diplomats from both sides had used their veto power.
However, the United States, the UK and France launched missile strikes against Syria as a response to the alleged chemical attack, despite the lack of evidence. The strike was launched on April 14, same day the OPCW mission was set to visit the sites.
