Iran says U.S. & U.K. responsible for assassination of scientist

(Reuters) - Iranian state television said on Saturday Tehran had evidence Washington was behind the latest assassination of one of its nuclear scientists. [...]
"We have reliable documents and evidence that this terrorist act was planned, guided and supported by the CIA," the Iranian foreign ministry said in a letter handed to the Swiss ambassador in Tehran, state TV reported.
"The documents clearly show that this terrorist act was carried out with the direct involvement of CIA-linked agents." [...]
State TV said a "letter of condemnation" had also been sent to the British government, saying the killing of Iranian nuclear scientists had "started exactly after the British official John Sawers declared the beginning of intelligence operations against Iran."

Apparently, the Iranian regime didn't coordinate their investigation with Reuters correspondent Dan Williams, who would have set them straight on the real culprit.
