More than 30,000 people have signed a petition to get an Egyptian woman who complained online about sexual harassment released from pre-trial detention.

Amal Fathy is due to appear before the Maadi Misdemeanours Court in Cairo on Saturday - but campaign group Amnesty International says it is unclear what charges Ms Fathy faces and is calling for her release.

“It is a shocking case of injustice. She is a human rights defender who told her truth to the world and wanted to highlight the vital issue of women’s safety in Egypt. She is not a criminal," says Amnesty's North Africa Campaigns Director Najia Bounaim.

In the video Ms Fathy uploaded earlier this year she criticised the Egyptian government for not doing enough to protect women and for providing what she says are poor public services.
