(February 11, 2007)—The US military says there's been a significant increase in the number of sophisticated roadside bombs in Iraq.
And a senior intelligence official says the orders to send components for them are believed to be coming from the Iranian government.
The officer briefed reporters in Baghdad on condition he not be identified.
He said that between June 2004 and last week, more than 170 Americans had been killed by what the military calls "explosively formed projectiles."
They're capable of destroying an Abrams tank.
The officer said American intelligence analysts believe the explosives are manufactured in Iran and smuggled into Iraq on orders from "highest levels" in the Iranian government.
