Iran rejects US ban on UN envoy

Iran on Saturday rejected a U.S. decision to deny a visa for its newly appointed ambassador to the United Nations, pledging to take up the case directly with the world body in a dispute that has reopened old wounds dating to the 1979 Islamic Revolution.

The United States, which hosts the United Nations, said Iran's candidate Hamid Abutalebi was unacceptable given his role in a 444-day crisis in which radical Iranian students stormed the U.S. embassy in Tehran and took 52 Americans hostage.

American law allows the Washington government to bar U.N. diplomats who are considered national security threats. But Obama's potentially precedent-setting step could open the United States to criticism that it is wielding its position as host nation to improperly exert political influence. 

The move also puts a strain on ongoing nuclear talks, but is unlikely to derail the negotiations. The nuclear negotiations have yielded unprecedented bilateral discussions between Iran and the United States. 

President Barack Obama had come under strong domestic pressure not to allow Abutalebi into the United States to take up his position in New York, raising concerns that the dispute would disrupt delicate negotiations between Tehran and six world powers -- including Washington -- over Iran's nuclear program.

Abutalebi says he served solely as a periodic translator for the Islamist students who seized the U.S. embassy hostages, and he has since evolved into a moderate figure favoring, like President Hassan Rouhani, a thaw in Iran's ties with the West.

"We have no replacement for Mr. Abutalebi and we will pursue the matter via legal mechanisms envisioned at the United Nations," said Abbas Araghchi, a senior Iranian Foreign Ministry official, according to IRNA news agency.

"Based on an agreement with the United Nations, America is bound to act according to its international commitments," Araghchi said, as quoted by IRNA. The United Nations said it had no comment at this time on the U.S. decision.

Araghchi is also a top negotiator in Iran's talks with big powers on defusing a stand-off over its disputed nuclear activity. Iran has said Washington's rejection of Abutalebi will not affect the talks.

The next round of negotiations is set for May 13.

Since an uproar among former U.S. hostages and U.S. lawmakers over Abutalebi broke out, Tehran has steadfastly stuck by its choice, describing him as a seasoned diplomat who has served in various capacities in Western countries.

"Dr. Abutalebi is one of the most capable, experienced and rational diplomats in Iran," Foreign Minister Mohammad Javad Zarif told IRNA. He served as Iran's U.N. envoy for eight years before taking his current job last year following Rouhani's election on a pledge to ease Iran's international isolation.

In comments posted on Facebook late on Friday, Abutalebi said the U.S. move against him set a "wrong new precedent."

Vahi Ahmadiah, a hardline conservative cleric who heads the Iranian parliament's foreign affairs and national security committee, said: "America has no right to inject its issues into an international matter. It has shown (here) its hostile nature again. It uses every chance to hit out at the Islamic Republic."

Iranian officials privately insist that the dispute should not be allowed to derail diplomacy aimed at a nuclear deal with world powers - crucial to Rouhani's promise to win Iran relief from punitive economic sanctions.

It was unclear whether the matter might play into the hands of hardliners in Iran's unwieldy power structure. They are keen to discredit Rouhani's campaign to improve long-hostile relations with the West, especially Washington, but have been held in check for now by Supreme Leader Ayatollah Ali Khamenei.

After former hostages objected to Abutalebi, members of Congress jumped to pass legislation this week banning him, seeing the issue as a chance to look tough on Iran after a new sanctions bill stalled in the Senate early this year.

Many Americans retain bitter feelings about Iran over the hostage crisis and many members of Congress, even Obama's fellow Democrats, are deeply skeptical about Tehran's intentions even under the pragmatist Rouhani. They treated Iran's selection of Abutalebi as a deliberate rebuke of the United States.
