Australian police have arrested 15 people in a massive anti-terrorism raid across three cities.
Around 800 police officers swept through dozens of locations in Sydney, Brisbane and Logan early Thursday, thwarting what officials called a domestic plot to "commit violent acts" against the public.
The arrests come days after Australia elevated its terror warning amid threats by Islamic State supporters.
Federal Folice Chief Andrew Colvin told reporters the group targeted by the raids "had started to carry out planning to commit violent acts here in Australia."
Last week, Australian police arrested two men in Brisbane suspected of preparing to fight in Syria, recruiting militants and raising money for the al-Qaida-affiliated al-Nusra Front.
