Iran's president has tried to ease concerns among neighbouring Arab states that Tehran could target them if armed conflict were to break out with the West over Iran's disputed nuclear programme.

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 US bases, fear that Tehran could attack them if a military conflict were to break out over Tehran's nuclear programme.

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