The US military displays seized weapons in Iraq, which it says were supplied by Iran to fuel the insurgency in the country. The U.S. military showed on Monday (February 26) what it said was further evidence Iranian-made weapons being used by Iraqi militants, including explosives linked to sophisticated roadside bombs. The weapons, which included mortar bombs and 122 mm rockets, were found during a raid by U.S. forces and Iraqi police on Saturday (February 24) near the volatile city of Baquba, north of Baghdad. Washington, which accuses Iran of fanning violence in Iraq, is particularly concerned about what it calls "explosively formed projectiles" -- bombs which, on detonation, shoot out a copper plate that becomes a large bullet-like projectile capable of penetrating armoured vehicles. The U.S. military say such bombs, which it calls EFPs, have killed 170 U.S. soldiers in Iraq since 2004. Military officials showed reporters in Baghdad 14 large rockets, 19 mortars and several bags of C4 plastic explosive they said were made in Iran since 2004. But they said there was no way to know if the Iranian government was involved in supplying them. Other parts of the cache, which officers described as a bomb factory or supply depot capable of turning out scores of EFPs, were not directly linked to Iran and their origin was unclear. U.S. officials said this month that the Quds Force, a unit of Iran's Revolutionary Guards, was supplying weapons to Shi'ite militia groups in Iraq. Tehran denies it fuels violence in Iraq.
