A news website in Egypt seen as one of the last independent voices in the country says that its editor has been arrested.

Mada Masr says that Lina Atallah was detained while conducting an interview with the mother of a leading activist and blogger, Alaa Abdel Fattah, outside the prison where he is being held.

Mada Masr says that Ms Atallah is now being held at a police station.

Last November, Lina Atallah and two other journalists were detained for several hours during a raid by the security forces on the Mada Masr office in Cairo.
