An Australian man has been jailed for two years in Lebanon for his involvement with a group accused of terrorist activity.

Imad Farouk Bsiso, a 35-year-old Jordanian-Australian from New South Wales, was one of seven men sentenced to jail for various offences related to terrorism, arms trafficking and forgery.

The military tribunal in Beirut found the men guilty of planning terrorist acts in Lebanon, trafficking weapons, and falsifying official documents.

Bsiso was sentenced to two years jail with hard labour, but with nine months deducted for time already spent in custody.

A Jordanian-New Zealand man was also jailed, along with two Palestinians.

Three other men, all Palestinian, are still on the run and were sentenced in their absence.
