The trial of Al-Jazeera journalists, Canadian Mohamed Fahmy and Egyptian Baher Mohamed, on terrorism-related charges has been postponed until 22 April.

Meanwhile, Cairo criminal court received a letter from the Canadian embassy enquiring into the status of Fahmy, who gave up his Egyptian citizenship in a bid to be deported.

The judge said the letter asked whether Fahmy was banned from travelling outside Egypt or not.

During Wednesday’s trial session, the judge asked Fahmy about his Canadian passport. He said it was taken from him the minute he was arrested in December 2013.

Fahmy and Mohamed were released from prison in February after spending over 400 days behind bars pending retrial.

The two journalists face charges of spreading false news and aiding the banned Muslim Brotherhood group, in a trial that has involved a total of 18 defendants.

Fahmy and Mohamed's conditional release came days after the deportation of their co-defendant, Australian journalist Peter Greste, on 1 February.

The three journalists were arrested in Cairo in December 2013 while covering the turbulent events Egypt witnessed in the aftermath of the ouster of Islamist president Mohamed Morsi.

The three journalists had initially been sentenced to 7-10 years in June 2014 before a court ordered a retrial in January 2015.
