The 16-year-old boy was charged with one count of planning a terrorist act after being arrested at his home in western Sydney yesterday, one day before Australians across the country gathered at ceremonies to mark ANZAC Day. The annual holiday commemorates the April 25, 1915, Gallipoli landings in Turkey -- the first major military action fought by the Australian and New Zealand Army Corps during World War I.
He would not release any other details of the alleged plot.
The teen was expected to face a children's court later today. He could face a maximum sentence of life in prison if convicted.
This is the second year in a row that police say they have stopped an attack on an ANZAC Day ceremony. Last year, police in Melbourne arrested five teenagers on suspicion of plotting an Islamic State group-inspired attack intended to coincide with the city's ANZAC service.
"Unfortunately, this is part of a pattern that we have been observing, where younger and younger people are targeted and incited to go and commit an act of terror," Keenan told reporters in Perth.
Australia's government raised the country's terror threat level in 2014 in response to the domestic threat posed by supporters of the Islamic State group. Police have since conducted dozens of raids they say have been aimed at thwarting multiple plots in Australia, including an alleged plan to attack government buildings and a naval base in Sydney.
