Top US military official: Iran boosting support for Iraqi insurgents

The top US military official says he is concerned about increased Iranian arms and training aid to insurgents in Iraq. Adm. Mike Mullen, the chairman of the Joint Chiefs of Staff, told a Defense Department news conference Friday that he has "no smoking gun" proof that the highest leadership in the Iranian government has approved of stepped up support for insurgents who are killing US and Iraqi forces. But he said that it is clear that recently made Iranian-made weapons are flowing into Iraq, including to insurgents leading the fight recently in Basra in southern Iraq. As Mullen put it, Iran "seems to be ratcheting things up."
