BBC NEWS - The most senior US general in Iraq has said he has evidence that Iran was behind Sunday's bombardment of Baghdad's heavily fortified Green Zone.
Gen David Petraeus told the BBC he thought Tehran had trained, equipped and funded insurgents who fired the barrage of mortars and rockets.
He said Iran was adding what he described as "lethal accelerants" to a very combustible mix.
There has as yet been no response from Iran to the accusations.
In an interview with BBC world affairs editor John Simpson, Gen Petraeus said violence in Iraq was being perpetuated by Iran's Quds Force, a branch of the Revolutionary Guards.
"The rockets that were launched at the Green Zone yesterday, for example... were Iranian-provided, Iranian-made rockets," he said, adding that the groups that fired them were funded and trained by the Quds Force.
"All of this in complete violation of promises made by President Ahmadinejad and the other most senior Iranian leaders to their Iraqi counterparts."
The barrage hit the Green Zone on Sunday morning. Some rockets missed their targets killing 15 Iraqi civilians.
Well General, the question is.....what are you going to do about it?
