From The Guardian:

British special forces operating on the border between Afghanistan and Iran have uncovered fresh evidence that Tehran is actively backing insurgents fighting UK troops.

Documented proof that Iran is supplying the Taliban with devastating roadside bomb-making equipment has been passed by British officials to Tehran, prompting fears that the war in Afghanistan may escalate into a regional armed conflict.

Days after Prime Minister Gordon Brown warned President Mahmoud Ahmadinejad that Britain would freeze the assets of Iran's largest bank to discourage Tehran from developing nuclear weapons, Whitehall sources revealed that they had forwarded 'documentation' that the Iranian authorities were supplying enemy forces in Afghanistan.

'We have given Tehran documentation of things that we are concerned about, but of course they have denied it,' a Whitehall source said.

Nato spokesman James Appathurai echoed concerns that elements in Iran are providing support to insurgents fighting British troops. He said: 'Weapons of Iranian origin have turned up in Afghanistan in significant numbers.' ...

Will anyone other than Mohamed ElBaradei cry over Tehran's suddenly missing nuclear project? Even the Saudis will be privately celebrating. The Russians aren't likely to do anything but wag a finger and the Chinese could care less. The UN will jump up and down, but it's been irrelevant since the fall of communism. The administration may express "regrets" and press Israel harder to give up more land for endless the "peace process," but that will happen anyway. The best window for Israel to take action is between now and November and I'm hoping they will.
