CAIRO -- Two media rights groups are calling on Egyptian authorities to investigate the death of a cameraman working for a Coptic Christian broadcaster who was shot in the head while filming clashes between the military and mostly Coptic protesters.

Wael Mikhael was among at least 26 people, most of them Christians, who died during Sunday's clashes in Cairo. The military has suggested at least two soldiers also died.

Reporters Without Borders on Thursday also condemned raids by Egyptian security forces on the U.S.-funded Al-Hurra TV and independent 25TV during their coverage of the clashes.

Meanwhile, the Committee to Protect Journalists says Egypt's state TV appeared to incite violence during its live coverage by calling on viewers to defend the military against attacks.
