TORONTO -- An Egyptian-Canadian journalist imprisoned in Cairo says he is not sure if he wants to appeal his conviction and go through the "circus" of a retrial.

Mohamed Fahmy was recently found guilty on terrorism-related charges along with two Al-Jazeera English colleagues in a trial denounced as a sham by a number of international observers.

He was working in Cairo as a bureau chief for Al-Jazeera English when he and his two colleagues -- Australian correspondent Peter Greste and Egyptian producer Baher Mohammed -- were arrested last December.

They were accused of supporting the outlawed Muslim Brotherhood and fabricating footage to undermine Egypt's national security -- allegations the journalists have denied, saying they were just doing their jobs.

Fahmy sent a letter through his fiancee to Canadian Journalists for Free Expression, saying he has not yet decided if he will appeal because he has "no faith in the judicial system," but he still believes in backroom diplomatic efforts.

Tom Henheffer, the group's executive director, says Fahmy is very tenacious and his letter shouldn't be taken as an indication that he's lost hope.
