On 27 November 2006, a senior American intelligence official told reporters that the Iranian-backed group Hezbollah had been training members of the Mahdi Army. The official said that 1,000 to 2,000 fighters from the Mahdi Army and other Shia militias had been trained by Hezbollah in Lebanon, and a small number of Hezbollah operatives have also visited Iraq to help with training. Iran has facilitated the link between Hezbollah and the Shia militias in Iraq, the official said. "There seems to have been a strategic decision taken sometime over late winter or early spring by Damascus, Tehran, along with their partners in ait Lebanese Hezbollah, to provide more support to Sadr to increase pressure on the U.S.," the American intelligence official said.
