Terror fight fear

Australians who fight with radical Islamic groups in Iraq and Syria could face up to 25 years jail when they return home, the Federal Government has warned.

Foreign Affairs Minister Julie Bishop said the Government was becoming alarmed at the number of Australians travelling to war zones in the Middle East, with fears fighters are being trained in combat and bomb-making skills.

She said the Government believes as many as 150 Australians had fought or were still fighting with opposition groups in Syria.

Ms Bishop said Australian laws could result in people being jailed for 25 years for fighting with a listed terrorist group.

The Government would also cancel or and refuse to issue passports where it was suspected a person was travelling to take part in fighting.

It is believed most of those who have travelled to war zones in recent years have come from Western Sydney or Melbourne.
