More than 100 people have been killed at a protest by supporters of ousted Egyptian President Mohammed Morsi in the capital Cairo, doctors say.
They said more than 1,500 were also hurt. The state health ministry says 38 people died and 180 were injured.
The army ousted Mr Morsi on 3 July. He has been formally accused of murder relating to a 2011 jail outbreak, and of links to the militant group Hamas.
