CANBERRA, Australia (AP) — Australian police have arrest warrants for two Australians who are fighting with the Islamic State group in Iraq and Syria after one posted photographs of the other posing with the severed heads of Syrian soldiers.

Australian Federal Police say Khaled Sharrouf and Mohamed Elomar are wanted for alleged "terrorism-related activity," and that the two will be arrested if they return to Australia.

The pair traveled to Syria late last year and then to Iraq to join the fighters. Australia says 150 Australians have fought with radical militants in Syria and Iraq.
