1938 alert from the [1] BBC, with thanks to Daffersd:

Britain has accused Iran of responsibility for explosions which have killed eight British soldiers in Iraq this year.

A senior British official, briefing correspondents in London, blamed Iranian Revolutionary Guards.

He said they provided the technology to a Shia group in southern Iraq. The Iranians had denied this, he added.

While UK officials have hinted at an Iranian link before, this is the first specific allegation to be made.
