Asylum seekers have rioted at an Australian detention centre in Sydney and set on fire many buildings.

Some of the detainees at Villawood centre also got onto the roof to unfurl banners and attacked firefighters and guards.

Rights groups said the long delays in the immigration applications process might have precipitated the violence.

But politicians condemned the actions as the "criminal behaviour" of people "not welcome" in Australia.
