Foreign Secretary William Hague has called for a "strong international response" to the use of chemical weapons in Syria.
Speaking on the BBC's Andrew Marr show, he said: "Allowing the spread and use of chemical weapons in the 21st century, is an evil that we have to stand up to, one way or another.
"If it is decided that no-one will stand up to chemical weapons, that will be an alarming moment in the affairs of the world."
He said Labour had behaved in an opportunistic way by voting against intervention, but added that the government would not be seeking another vote on the matter:
"Our parliament has spoken. It is therefore up to other parliaments and they are about to speak."
