Mahmoud Hussein, an Egyptian citizen and a journalist working with Al Jazeera, was arrested in December while on holiday.
He has been accused of broadcasting false news to spread chaos, which Al Jazeera strongly denies.
Al Jazeera is concerned for his health and is demanding his immediate release.
Recent video footage of him outside the courthouse, shows he has lost weight and looks exhausted due to harsh detention conditions. He is being kept in solitary confinement.
