Hizbullah group is training Iraqi Shiite extremists in camps near the Iranian capital of Teheran, a US military spokesman said Monday. Iran's elite Quds Force of the Revolutionary Guard is operating these camps. The group is also sending weapons to these militias in Iraq. Air Force Col. Donald Bacon said Monday that the information comes from interrogations of detainees. Washington has long accused Tehran of destabilizing Iraq by supporting Shi'ite militias. Iran denies the charge.
