US accuses Iran over Iraqi Shias
The US military commander in Iraq has accused Iran of providing covert support to Shia extremists in Iraq.
Iran equips and trains Shia militia groups, Gen George Casey said, adding that its influence had risen recently.
Although the US has no evidence that Iranians were operating directly in Iraq, Gen Casey said "surrogates" regularly attacked US troops.
The US has often accused Iran of aiding Shia groups in Iraq, but has previously offered little proof.
Speaking alongside Defence Secretary Donald Rumsfeld at the Pentagon, Gen Casey said intelligence now backed previous previously-held suspicions.
"Since January we have seen an upsurge in their support, particularly to the Shia extremist groups," he said.
"They are using surrogates to conduct terrorist operations both against us and against the Iraqi people."
Talks suspended
Gen Casey singled out Iranian influence as one of four major factors in the complex security situation inside Iraq.
"We are quite confident that the Iranian, through the special operations forces, are providing weapons, IED [improvised explosive device] technology and training to Shia extremist groups in Iraq," he said.
Training was probably carried out in Iran and possibly in Lebanon, Gen Casey said.
He suggested that Lebanon's Iranian-backed Hezbollah guerrillas were also likely to be involved in training Iraqi militias. Direct talks between the US and Iran over the security situation in Iraq have been suspended.
Iran accused the US of exploiting the issue amid continuing diplomatic wrangling over Iran's nuclear programme.
