Sunday March 14 8:05 AM ET U.S. Jets Bomb Iraqi Artillery In North ANKARA, Turkey (Reuters) - U.S. warplanes bombed Iraqi air defenses in the no-fly zone over northern Iraq Sunday, said a spokesman at the base in southern Turkey from which the jets operate. He told Reuters the planes dropped an unspecified number of bombs after ``aircraft observed Iraqi anti-aircraft artillery fire and detected Iraqi radar posing a threat to coalition aircraft.'' Such strikes have been common since Iraq decided in December actively to oppose U.S. and British jets patrolling the no-fly zones in the north and south of the country. The jets flying out of the Incirlik airbase patrol a mountainous Kurdish-held enclave and a swath of Baghdad-controlled territory around the city of Mosul. ``F-15E Strike Eagles dropped GBU-12 laser-guided bombs on several anti-aircraft artillery sites northwest and west of Mosul,'' the spokesman said. Friday jets from Incirlik also bombed anti-aircraft artillery sites after detecting Iraq radar tracking the aircraft. Iraq does not recognize the Western-enforced zones set up after the 1991 Gulf War to protect the Kurdish area in the north and Shi'ite Muslims in the south. NATO-member Turkey hosts the force, known as ``Operation Northern Watch,'' but has expressed concern in recent months over the policy of close ally the United States toward Turkey's southern neighbor Iraq.
