Documents Say Iran Aids Militias From Iraq

Such is a typical day at a dusty military base outside Tehran, where for the past several years members of the Iranian Revolutionary Guard Quds Force and Lebanese Hezbollah operatives have trained Iraqi Shiites to launch attacks against American forces in Iraq, according to accounts given to American interrogators by captured Iraqi fighters.

American officials have long cited Iranian training and weapons as reasons for the lethality of attacks by Shiite fighters in Iraq. Iranian officials deny that such training takes place.
