Foreign Secretary David Miliband says Britain and Iran have agreed to resolve the dispute over the arrest of four local British Embassy staff in Tehran, Press TV reported.
The Tuesday announcement came one day after Iran's Foreign Ministry confirmed that five of the nine detainees had been released following primary investigation into their alleged role in 'inciting mass public protests' following the June 12 vote.
Miliband told parliament that the decision had been reached for the safekeeping of the interests of both countries and expressed concern over the "continued detention of some of our locally engaged staff in Tehran."
"I have discussed this issue with Iranian Foreign Minister (Manouchehr) Mottaki and we both agreed in our second telephone conversation yesterday that a swift resolution was in both of our interests," Miliband said, calling for the release of the remaining Embassy employees.
The announcement of the Mahmoud Ahmadinejad's re-election sparked opposition rallies in the capital Tehran with defeated candidates Mir-Hossein Mousavi and Mehdi Karroubi rejecting the result as fraudulent and demanding a re-run.
Iran has lashed out at foreign 'interference' in its internal affairs, saying the 'biased' attitude of European countries and their media incited the post-election unrest.
