An Australian correspondent was one of four journalists in custody in Egypt on Sunday night.
The al-Jazeera news network said four journalists working for its English news channel, including Australian Peter Greste, had been detained in Cairo after being arrested by security forces.
The news network did not give any further details but The New York Times reported the group was arrested for meeting with members of the Muslim Brotherhood, which was declared a terrorist organisation last week.
The other journalists included producers Mohamed Fahmy and Baher Mohamed, as well as cameraman Mohamed Fawzy.
The journalists "broadcast live news harming domestic security," Egypt's interior ministry said, adding they were also found in possession of Muslim Brotherhood ‘‘publications’’.
Peter Greste left Australia in 1991 to become a foreign correspondent and has worked with Reuters, CNN and the BBC.
He won a prestigious Peabody Award in 2011 for a documentary about Somalia.
In a story on its website, al-Jazeera demanded the immediate release of their journalists.
