Syrian president Bashar al-Assad has said claims his regime launched a fatal gas attack on his own citizens is '100 per cent fabrication'.

Assad told AFP the suspected chemical weapons attack on a rebel-held town was a lie to justify a US military strike.

He made the comments in an interview, less than 24 hours after world leaders clashed over the attack on the war-torn country.

Assad, in his first interview since American missiles hit a central Syrian air base earlier this week, said he felt the US was “hand-in-glove with the terrorists” and accused the US government of making up the story in order to have a pretext for the attack.

“'Definitely, 100 per cent for us, it's fabrication... Our impression is that the West, mainly the United States, is hand-in-glove with the terrorists. They fabricated the whole story in order to have a pretext for the attack,” he told AFP.
