BAGHDAD (Reuters) - Iran has postponed a fourth round oftalks with the United States in Baghdad on improving securityin Iraq, prompting U.S. officials on Thursday to questionTehran's commitment to the dialogue.
Iran's ambassador to Baghdad blamed "technical issues" forthe last-minute delay to discussions that were to be held onFriday, but did not elaborate.
The U.S.-Iranian security talks are one of the few forumsin which officials from the two bitter foes have directcontact. Diplomatic ties between Washington and Tehran havebeen frozen for almost three decades.
Iraqi Foreign Minister Hoshiyar Zebari called the Iranianpostponement "unfortunate".
"Yesterday we were informed that the Iranians want topostpone this for some time. This is the fourth time that weagreed on a date and they don't show up," Zebari told Reuters.
Iraq later said Iranian President Mahmoud Ahmadinejad wouldvisit Baghdad on March 2 for talks with Iraqi Prime MinisterNuri al-Maliki and other senior officials in what would be thefirst visit by a president of the Islamic Republic.
U.S. and Iranian officials met three times last year toseek common ground on stabilising Iraq in talks arranged by theBaghdad government. The last time was in August.
Washington has used the talks to urge Iran to stop givingweapons and training to Shi'ite militias in Iraq, includingarmour-piercing bombs known as explosively formed penetrators(EFPs) that have killed hundreds of U.S. troops.
Tehran denies the charges and blames the U.S.-led invasionof Iraq in 2003 for violence in its neighbour. Both sides arealso embroiled in a row over Iran's nuclear ambitions.
Hassan Kazemi-Qomi, Iran's ambassador to Iraq, said Tehranstill wanted to hold the talks.
"This was supposed to take place on this week's Friday, butbased on latest evaluation and because of technical issues,these negotiations have been postponed," he told the officialIranian news agency IRNA.
U.S. SAYS IT'S READY
U.S. embassy spokeswoman Mirembe Nantongo said it appearedIranian officials were unwilling to meet their U.S.counterparts.
"We have been ready for weeks. We are happy to sit down forthe talks but it's increasingly clear Iran is not," she said.
Iraqi government spokesman Ali al-Dabbagh told ReutersTehran had requested a postponement of a "few more days".
Zebari said all sides saw value in the dialogue, addingIran had been helping stem violence in Iraq, partly by stoppingsome weapons coming across the border.
He also said Iran had been influential in reining in theactivities of the Mehdi Army militia of Shi'ite cleric Moqtadaal-Sadr. The anti-American cleric declared a ceasefire lastAugust that has been credited with helping cut violence.
"The number and amount of weapons and EFP technology, lessis coming across the border, according to the Americans and toour intelligence. So on these two accounts they have beenhelpful," Zebari said.
"It doesn't mean they are not interfering and notintervening. This is a friendly government to Iran and it wouldbe contradictory for them on the one hand to support thegovernment and on the other hand to support the militias."
Iran and Iraq fought an eight-year war in the 1980s inwhich hundreds of thousands were killed, but ties have improvedsince Saddam Hussein was ousted in the U.S.-led invasion ofIraq in 2003 and a Shi'ite Islamist-led government came topower.
Dabbagh said Ahmadinejad would visit Iraq for two days atthe invitation of President Jalal Talabani.
"It's significant in the sense that Iraq wants to have goodrelations with Iran (but) there should be no interference inIraq's internal affairs," Dabbagh said of the visit.
White House spokesman Gordon Johndroe said the U.S.government wanted the two countries to have good relations.
"The fastest way for that to happen is for Iran to stopsupporting extremists in Iraq who kill innocent Iraqis andAmericans," he said in a statement.
