Egypt's Muslim Brotherhood said at least 250 people were killed and over 5,000 injured on Wednesday in a police crackdown on two major protest camps held by supporters of ousted president Mohamed Morsi.
"250+ confirmed deaths. Drs saying most critical patients will die from their bullet wounds. over 5000 wounded. biggest massacre since #coup," Brotherhood spokesman Gehad al-Haddad said on Twitter.
There was no independent confirmation of the Brotherhood toll.
An AFP correspondent at the Rabaa al-Adawiya protest camp had counted 17 bodies at the makeshift morgue in Cairo.
