MEPs have called for a “clear and strong” international response to last month’s chemical weapons attack that left more than 1,000 people dead.
The motion, passed at the European Parliament in Strasbourg, also raised the possibility of “eventual deterrent measures”.
But the Belgian representative of the opposition Syrian National Council said the resolution misses the point.
Georges Chachan told euronews: “To be honest, we are tired of indignation. Since the start of this crisis, the Syrian regime and the Russians have been one step ahead of everyone. It is sad to see now that the regime is waging against its people has transformed into negotiations about controlling chemical weapons.”
Syrian president Bashar al-Assad has confirmed that he would surrender his country’s chemical arms.
Just three days ago, he denied possessing any such weapons in an interview with a US television network.
