An Islamist extremist group in Sydney has asked if the federal government is planning concentration camps for Muslims.
Hizb ut-Tahrir compared Australia's internment of Japanese and German prisoners of war during the 1940s with perceived modern-day hostility towards Muslims.
'Startling Australian history. Germany wasn't the only country with concentration camps,' spokesman Hamzah Qureshi said in a Facebook post.
Mr Qureshi put Australia's detention of prisoners of war, in country New South Wales and Victoria, in the same sentence as Nazi concentration camps.
