One of Australia's most prestigious universities has become the centre of a movement that believes Syrian dictator Bashar al-Assad has been framed by the West for last week's chemical weapons attack.

The University of Sydney is standing by a controversial senior lecturer, Tim Anderson, who has dismissed the sarin gas attack in the Idlib Province as a "hoax" and called Syria's six-year civil war a "fiction" perpetrated by the US "to destroy an independent nation".

Fairfax Media can reveal Dr Anderson is just one among a number of Australian academics who have formed a pro-Assad outfit called the Centre for Counter Hegemonic Studies, based in Sydney, to counter "censorship" by their universities.

The centre was formed "after concern that many Western academic bodies constrain, censor and marginalise counter-hegemonic or anti-imperial research and discussion, due to their close ties with government and corporate sponsors".
