CANBERRA, Australia – Five men have been arrested on suspicion that they planned to leave Australia in a seven-meter (23-foot) boat to fight in Syria, police said Wednesday.
The men, aged 21 to 33, had towed the half-cabin power boat with a car 2,800 kilometers (1,700 miles) from their homes in the southern city of Melbourne to Cairns in Australia's tropical north were they were arrested Tuesday, police said.
All had their passports canceled to prevent them leaving the country to fight for extremist groups such as the Islamic State movement.
The men were being held on suspicion of breaking a federal law banning foreign incursions, Australian Federal Police Deputy Commissioner Neil Gaughan said. Entering or preparing to enter a foreign country to engage in a hostile activity is a crime punishable by life imprisonment.
Victoria Police Deputy Commissioner Shane Patton said the men planned to travel by boat through Indonesia to the Philippines. He did not specify how they planned to get from the Philippines to Syria.
"This is a serious attempt by five men who are of security interest to us who have had their passports canceled in attempting to exit Australia ... and then ultimately we're investigating the intention to possibly end up in Syria to fight," Patton told reporters.
"We can't allow Australians to leave Australia and support terrorism anywhere," he said.
The men had been under police investigation for weeks. Police would not say when they left Melbourne or where they intended to leave Australia.
Gaughan said the men were known to have "extremist views." Police declined to identify them.
Security officials estimate 110 Australians are fighting for the Islamic State group in the Middle East.
