Seven photographers and a cameraman have been detained in Iran over the past week, media monitor Reporters Without Borders said.

The Paris-based group listed five Iranian photographers seized Saturday, nearly a month after the June 12 presidential elections that prompted a wave of opposition protests. It says French-Iranian cameraman Said Movahedi was detained July 9.

The reason for the arrests is unclear.

Reporters Without Borders said in a statement Thursday that "The Iranian government fears images" of the protests.

The group says at least five other photographers or cameramen have been injured by police or militias during the crackdown on opposition protesters. It says 41 journalists are behind bars in Iran.
