In an effort to help the United States counter al-Qaida after the 9/11 attack, Iran rounded up hundreds of Arabs who had crossed the border from Afghanistan, expelled many of them and made copies of nearly 300 of their passports, a former Bush administration official said Tuesday.

The copies were sent to Kofi Annan, the U.N. secretary-general, who passed them on to the United States, while U.S. interrogators were given a chance by Iran to question some of the detainees, Hillary Mann Leverett said in an Associated Press interview.

Leverett, who said she negotiated with Iran for the Bush administration in the 2001-3 period, said Iran sought a broader relationship with the United States. "They thought they had been helpful on al-Qaida, and they were," she said.

For one thing, she said, suspected al-Qaida operatives were not given sanctuary in Iran.

Some administration officials took the view, however, that Iran had not acknowledged all likely al-Qaida members nor provided access to them, Leverett said.

Many of the expelled Arabs were deported to Saudi Arabia and to other Arab and Muslim countries, even though Iran had poor relations with the Saudi monarchy and some other countries in the region, Leverett said.

James F. Dobbins, the Bush administration's chief negotiator on Afghanistan in late 2001, said that Iran was "comprehensively helpful" in the aftermath of the 9/11 attack in working to overthrow the Taliban and collaborating with the United States in installing the Karzai government in Kabul.

Iranian diplomats made clear at the time they were looking for broader cooperation with the United States, but the Bush administration was not interested, the author of "After the Taliban: Nation-Building in Afghanistan," said in a separate interview.

The Bush administration has acknowledged contacts with Iran over the years even while denouncing Iran as part of an "axis of evil" and declining to consider a resumption of diplomatic relations. Continued...
