A Canadian man who was deported by U.S. officials to Syria, where he was imprisoned and allegedly tortured, has appealed a court ruling preventing him from suing the U.S.

Maher Arar filed a lawsuit before the U.S. supreme court on Monday, appealing a lower court ruling that rejected his case because it involved national security information.
Arar was arrested by U.S. authorities while transiting through New York's JFK International Airport in 2002, on his way home to Canada from a family vacation in Tunis.
He was detained on information shared by Canadian police that suggested he had ties to ""terrorist"" groups.
Canadian commission eventually cleared him of any connections to ""terrorist"" organizations and concluded that he had been tortured.
He was awarded $10.5m in compensation. (Source: Al Jazeera)
