BAGHDAD (Reuters) - Iraq on Friday vowed to continue firing at Western planes patrolling no-fly zones over the southern and northern parts of the country. "Iraq is determined not only to defy the U.S.-British continued aggression on its lands but also endeavours to inflict any possible heaviest damage to the aggressors," Al-Thawra, mouthpiece of the ruling Baath party said. Thawra also put blame on the United Nations for its silence over the U.S. and British air strikes against Iraqi military targets which became commonplace after Baghdad decided in December to attack U.S. and British jets patrolling the zones. Iraq does not recognise the no-fly zones, set up after the 1991 Gulf War to protect Kurds in the north and Shi`ite Moslems in the south from possible attack by Baghdad`s forces. Baghdad said on Thursday its air defences opened fire at Western warplanes patrolling the south of the country. Since last December, Iraq`s military command has regularly been announcing that it is opening fire on U.S. and British planes. The allies say they have suffered no losses. Senior ruling Baath party member Abdul-Ghani Abdul-Ghafour called on the Arab League to advise Saudia and Kuwait not to give facilities for Western planes to attack Iraq. "The Arab masses and the Arab League are called on to play a role in halting the behaviour of the Kuwaiti and Saudi rulers... in making Saudi and Kuwaiti lands and waters a springboard for the enemy aggression on Iraq," Abdul-Ghafour said. The U.S. and Britain maintain military forces in the two Gulf states used for air strikes against Iraq.
