Lawyers for the three Al Jazeera staff jailed in Egypt have filed an appeal against their conviction, citing several “breaches of process” in their case.

• Advisor: who is Peter Greste?

Australian Peter Greste and his colleagues Baher Mohamed and Mohamed Fahmy were imprisoned and charged with spreading false news, placing national security at risk and supporting the Muslim Brotherhood.

According to an Al Jazeera report, their case will now be heard before the Court of Cassation to examine the grounds for a full hearing.

Lawyers for the men have accused Egyptian authorities of using a flawed arrest procedure and irrelevant evidence.

They also added that judge who delivered the verdict mentioned the journalists’ lack of accreditation, which is not a criminal offence.

“The appeal will lay bare the flaws in the case against Peter, Baher and Mohammed,” Al Anstey, Al Jazeera’s managing director, said.

“These are three outstanding journalists who were just doing their jobs.

“We look forward to them being exonerated in due course. We will not stop in this quest till they are reunited with their families.”

The trio were found guilty of the offences in an Egyptian court on June 24.
