The UK has put forward a resolution at the UN Security Council “authorising all necessary measures to protect civilians" in Syria.
There has been increasing pressure on the international community to act after chemical weapons were used, however it has not yet been conclusively proven where the weapons were fired from.
Russia has said the UN must finish its investigations before the resolution can be discussed. Secretary General Ban Ki-moon has also appealed for more time for the team to do its job.
Syria has denied the claims.
"Western countries, starting with the United States, are inventing fake scenarios and fictitious alibis to intervene militarily in Syria," Prime Minister Wael al-Halqi said on Syrian state television.
