Mawlud Afand, the editor-in-chief of the Israel-Kurd Institute's magazine, has been missing since June 8, said Diyari Mohammed, a correspondent for the magazine in Sulaimaniyah, in the autonomous Kurdistan region of northern Iraq.
Media watchdog Reporters Without Borders expressed concern about the missing journalist.
"We fear the worst and we urge the autonomous Kurdistan Regional Government's authorities to do everything possible to find Afand," the group said in a statement on its website, calling for an immediate investigation.
During a visit to Sulaimaniyah, Afand "went alone for an appointment... and disappeared," Mohammed said.
"He called in the afternoon the next day and told us that he was on a private visit and would return back after a week," he said.

A woman who spoke Persian answered Afand's phone on June 13, but it has been switched off since then, Mohammed said, adding Afand's colleagues have raised the possibility he was kidnapped by Iranian intelligence.
Mohammed said the president of the Israel-Kurd Institute, Dawood al-Baghistani, had been informed by the Kurdistan region's government last year that Iran wanted the magazine closed, but that Kurdistan declined to do so.
RSF said the magazine "promotes better relations between Israelis and Kurds and encourages Kurdish Jews who immigrated to Israel to return to Kurdistan," noting that "its aims and activities are controversial and constitute a major source of discord between the Kurdistan Regional Government and Iran."
