Mick Deane, a British photojournalist for Sky News, was killed while covering the breakup of the Rabaa al-Adaweya sit-in, the Egypt Independent quoted a report as saying.
A report by the Health Insurance hospital in Nasr City said Deane, 61, died after being shot in the heart.
The Health Ministry said 13 people were killed near the Rabaa al-Adawiya mosque during a military crackdown, including five police and eight civilians. The official death toll could well rise.
