Australia launches anti-terror raids in Sydney and BrisbaneAustralian police have made 15 arrests in Sydney and Brisbane, in what they say is the nation's biggest counter-terrorism operation.
At least 800 heavily armed officers raided properties in the two cities.
Police said the operation disrupted plans to "commit violent acts". One reported plan was the random beheading of a member of the public.
The terror threat is high because of concern over the domestic impact of the Iraq and Syria conflicts.
