The station said gunmen kidnapped the cameraman Friday along with three other employees of the pro-regime Al-Ikhbariya TV.
A video surfaced online Monday, showing the three surviving members of the team. They said they were being held by rebel forces, who were treating them well.
A man who identified himself as a rebel spokesman also appeared in the video, saying the cameraman was killed in government shelling. The general manager of Al-Ikhbariya TV said they believe he is dead.
