Hundreds of Coptic protesters gathered outside Egypt's state television building in Cairo on Sunday.
The demonstrators say they are angry at state media for not reporting the burning of a church during a sectarian conflict in a town south of Cairo on Saturday.
The protesters were surrounded by a line of military police wearing riot gear.
Crosses were held aloft by many of the crowd. Some priests were also present.
A number of small scuffles broke out, but it was not clear what exactly triggered them.
The stretch of the Corniche in front of the TV building is closed to traffic.
