Pentagon Widens Program to Foil Bombings in Iraq - New York Times:

So, we learn that Iran has a hand in killing Americans and Iraqis by furnishing IEDs and know-how to Shia in Iraq.

"Some of the most deadly bombs use shaped charges, which penetrate armor by focusing explosive power in a single direction and by firing a metal projectile embedded in the device into the target at high speed. American intelligence officials say the most potent of these new weapons have been designed in Iran and shipped to Iraq from there.
'Tehran has been responsible for at least some of the increasing lethality of anticoalition attacks by providing Shia militants with the capability to build improvised explosive devices with explosively formed projectiles similar to those developed by Iran and Lebanese Hezbollah,' Mr. Negroponte told senators last week.
The American military adviser team to Iraqi special police forces in Salman Pak, 12 miles southeast of Baghdad, said it had been seeing more sophisticated shaped-charge explosions since last spring. A senior Army intelligence officer said the charges were being used mostly by Shiite militia groups, but added, 'Our fear is that the technology will migrate to Sunni insurgent groups.'"
