Russia rejected a new US proposal at the United Nations today to set up an investigation to identify the perpetrators of chemical weapons attacks in Syria.
The United States put forward a draft resolution to the Security Council following alleged toxic gas use in the rebel-held town of Douma that killed at least 40 people.
The US push for a new inquiry came amid heightened tensions over possible US military action in Syria, with President Donald Trump saying that "major decisions" would be taken within 48 hours.
Russian Ambassador Vassily Nebenzia said the US-drafted measure "contains some unacceptable elements, which make it worse" than a previous US proposal put forward in March.
"From what we hear now, I am afraid they are looking for a military option, which is very, very dangerous," he told reporters following an emergency council meeting.
Trump -- who last year launched a missile strike on a Syrian air base after sarin was used in the town of Khan Sheikhun -- warned after the latest accusations that there would be a "big price to pay."
"Either way, the United States will respond."
"All sides know what is going on, and the Russians have actually been predicting US military action over Ghouta for some time. We just have to hope that Moscow will not overreact when the strikes come."
