LOUISVILLE, Ky. (AP) — An Iraqi refugee living in Kentucky told an FBI informant he used improvised explosive devices in insurgent attacks on U.S. troops in Iraq and is accused of trying to send sniper rifles and Stinger missiles to his home country, according to a sworn statement. The refugee, along with one of his recruits, was arrested and is accused of trying to send the weapons and money to al-Qaida operatives in Iraq. Waad Ramadan Alwan, 30, was well-schooled in sniper rifles and improvised explosive devices, according to an FBI affidavit released Tuesday.
