DOHA, Qatar (AP) - Iran's president has tried to ease concerns among neighboring Sunni Arab states that Tehran could target them if armed conflict were to break out with the West over Iran's disputed nuclear program.

Mahmoud Ahmadinejad said Sunday during a trip to the tiny Gulf emirate of Qatar that there is a need for "comprehensive reconciliation and vast cooperation" between Shiite-dominated Iran and other Gulf nations.

Many of Iran's Sunni Arab neighbors, some of which host U.S. bases, fear that Tehran could attack them if a military conflict were to break out over Tehran's nuclear program.

Western powers believe Iran's nuclear program aims to develop atomic weapons. Iran denies the allegations and says its program is for peaceful purposes.
