The Russian-made Sukhoi 22 crashed near Ajdabiya, 160 kilometers west of the city which has fallen to anti-regime protesters, a military source said, quoted in Quryna newspaper.

Iran's president said Wednesday he is certain the wave of unrest in the Middle East will spread to Europe and North America, bringing an end to governments he accused of oppressing and humiliating people.

The Arab League on Tuesday barred Libya from its meetings until Tripoli responds to the demands of protesters, threatening to suspend its membership after clashes that have killed hundreds.

It was the second time Gadhafi has appeared during the week of upheaval across his country.
