DOHA (AFP) - Iranian Defense Minister Ali Shamkhani warned that Iran might launch a preemptive strike against US forces in the region to prevent an attack on its nuclear facilities. "We will not sit (with arms folded) to wait for what others will do to us. Some military commanders in Iran are convinced that preventive operations which the Americans talk about are not their monopoly," Shamkhani told Al-Jazeera TV when asked if Iran would respond to an American attack on its nuclear facilities. // clip
