| Iraq's military has in recent days moved anti-aircraft missiles into northern and southern "no-fly" zones to an extent not seen in years. But Air Force Gen. Richard Myers, chairman of the Joint Chiefs of Staff, told a Pentagon briefing the air defense build-up in the two Iraqi zones policed by U.S. and British warplanes appeared simply to be part of "episodic" movements in and out of the areas. Myers noted the western jets attacked air defenses in the zones twice last week in response to threats from the ground, but did not suggest exchanges were increasing after more than a decade of patrols prompted by the 1991 Gulf War. |
