Iraqi officials say the government has dispatched a delegation to Iran to discuss concerns about the arming and training of Shi'ite militias in Iraq. A government official says five Shi'ite politicians left Wednesday with "evidence, confessions and pictures" indicating that Iran is supplying weapons and training fighters who are locked in a violent standoff with US and Iraqi troops. The official says the delegation "will seek to clarify...the interference of Iranian leaders." The official spoke Thursday on condition of anonymity because he wasn't authorized to release the information. Senior Shi'ite lawmaker Reda Jawad Taqi confirms the delegation was sent but did not provide more details.
