Journalist Peter Greste RELEASED from prison in Egypt after 400 days behind bars.

Australian journalist Peter Greste has been released from Egyptian prison and is on his way back to Australia after more than a year behind bars.

Mr Greste was freed by order of Egypt's president Abdel Fattah al-Sisi, under a new law that allows foreign prisoners to be deported.

His brother Andrew Greste confirmed the Al-Jazeera reporter 'has left Egyptian airspace' and will arrive home in Brisbane on Monday.

His overjoyed sibling wrote on Twitter: 'Hard to believe but YES @PeterGreste is a free man. His butt has left Egyptian airspace yippeeeeee!!!!! Think I'll go and get drunk :):):).'

Mr Greste arrived in Larnaca, Cyprus, on Sunday night after flying out of Cairo on an EgyptAir flight alongside one of his brothers. 

The family was ecstatic and called for the world to respect his brother's privacy and to give him time to appreciate his freedom.

A Canadian journalist also being held in Egypt will also be released 'within days', security officials have revealed.Congrats to him.
