The defence maintained that the journalists were wrongly arrested and that the prosecution had failed to prove any of the charges against them.
'Absurd allegations'
Al Anstey, Al Jazeera English managing director, said the verdicts defied "logic, sense, and any semblance of justice".
"Today three colleagues and friends were sentenced, and will continue to be kept behind bars for doing a brilliant job of being great journalists. 'Guilty' of covering stories with great skill and integrity. 'Guilty' of defending people’s right to know what is going on in their world," Anstey said in a statement.
"Peter, Mohamed, and Baher and six of our other colleagues were sentenced despite the fact that not a shred of evidence was found to support the extraordinary and false charges against them. At no point during the long drawn out 'trial' did the absurd allegations stand up to scrutiny.
"There is only one sensible outcome now - for the verdict to be overturned, and justice to be recognised by Egypt."
