Iran's foreign ministry spokesman said Sunday that five of the country's officials held by the US in Iraq have complained about their treatment in detention.
Mohammad Ali Hosseini's comments come a day after Iranian diplomats met with their detained countrymen in Iraq for the first time.
"The five [detained] diplomats during the meeting were complaining about the Americans regularly breaking promises for their release," Hosseini said during his weekly news briefing. "This was one of the psychological pressures that they complained about."
Hosseini did not provide additional examples of psychological pressure, and it was unclear to which promises he was referring. The US has not publicly promised to release the five Iranians, who were detained on January 11 in the northern Iraqi city of Irbil.
