Another Calgary man has joined the ranks of radical Islamic terrorists overseas, CTV News has learned.

Farah Mohamed Shirdon is seen in a recent video released by the Al-Qaeda linked terror group ISIS.

In the video he is seen uttering threats against Canada and the U.S. and also burns his Canadian passport.

ISIS, a well-equipped and well-organized terror group, invaded Iraq and quickly spread, seizing key cities and attempting to assume control of the country’s oil resources.

The group has been a steadily-growing problem in both Iraq and Syria since last December, but attacks escalated earlier this month when 800 ISIS fighters captured the Iraqi city of Mosul.

Shirdon would be the third Calgarian recruited by terror groups fighting in Iraq and Syria.

Earlier this month, CTV confirmed that Salman Ashrafi, a former student leader at the University of Lethbridge, was killed in a suicide attack on a military facilty in Iraq, taking 46 people with him.

In January, another Calgarian, Damian Clairmont was killed in a shootout with government forces in Syria.

Clairmont, who also went by the name Mustafa Al-Gharib, converted to Islam following a suicide attempt, and then left for Syria in November 2012.

Clairmont’s mother says her son and Ashrafi were friends and were sought out, ‘brainwashed’, and coerced into joining radical movements of Islam.
