Mohamed Fahmy, a Canadian journalist with Al-Jazeera television freed from an Egyptian jail last month after a presidential pardon for broadcasting "false" news, announced Tuesday he was flying home.

"Canadian Ambassador Troy (Lulashnyk) kindly escorted me to the gate at Cairo airport. A glorious end to our battle for freedom!" he tweeted.

An airport security official confirmed that Fahmy had boarded a flight bound for London.

Fahmy, along with colleagues Baher Mohamed and Peter Greste, who was deported at the beginning of the year, were convicted in an August retrial of fabricating "false" news in support of the banned Muslim Brotherhood.

They were sentenced to three years.

President Abdel-Fattah El-Sisi pardoned Fahmy, Mohamed and 100 other prisoners last month.

The status of Greste, an Australian, is still unclear.
