TEHRAN: Iran's Foreign Ministry Spokesman Hassan Qashqavi said on Sunday that there is no link between the release of Iranian diplomats and the US-Iran direct talks, the official IRNA news agency reported.

"The measure (of releasing diplomats) has nothing to do with direct talks between Iran and the United States and is not of prime importance in diplomatic ties between the two sides," Qashqavi was quoted as saying.

Five Iranians, including three diplomats, who were freed by the US military after more than two years in detention, arrived in Tehran on Sunday, local English-language Press TV reported.

The Iranians arrived in Tehran's Mehrabad Airport and were welcomed by Iranian Foreign Minister Manouchehr Mottaki and their family members.

"US kidnapping of Iranian diplomats was an inhuman act," Mottaki told reporters in the airport, adding that "we reserve the right to legally follow up this kidnapping case."

On January 11, 2007, the US troops raided the Iranian Liaison Office in Iraq's Kurdish city of Arbil, capturing five mid-level diplomats, two of whom were later released, Press TV said.

Two other Iranians kidnapped elsewhere in Iraq by the US troops later joined the three diplomats in detention, said the report.

The US military said the Iranian Liaison Office was used by the Iranian Revolutionary Guards as a local headquarters. However, both Iranian and Kurdish autonomous region officials denied the accusation, insisting that the target was a diplomatic mission.
