Mullen renews accusations Iran arming anti-U.S. forces in Iraq

"... Adm. Mike Mullen, the chairman of the Joint Chiefs of Staff, made the accusation in a roundtable with members of the Pentagon Press Association on the same day that two American service members were killed in Baghdad, apparently the victims of a bomb known as an explosively formed penetrator, a type of weapon that U.S. officials say comes from Iran."Iran is very directly supporting extremist Shiite groups, which are killing our troops," Mullen said.
Mullen said the United States and Iraq were discussing whether some American troops should stay in Iraq after a Dec. 31 deadline ...
American officials last charged Iran with providing weapons to Shiite militias in 2005 and 2006, ... in recent months, American officials have renewed their accusations. Mullen said Thursday that in addition to explosively formed penetrators, Iran was providing Iraqis with "improvised rocket-assisted mortars," essentially improvised bombs attached to rockets. Mullen suggested that the weapons were being provided to gain favor with the militias, which operate primarily in Iraq's south. "There's no question they want influence, particularly in the south," Mullen said...."
