The complaint to UN Secretary-General Ban Ki-moon turned the US accusation that Tehran supports terrorism back onto Washington, Salehi said.

“This letter contains our complaint about the plots of the United States, reliable information that we have of the US involvement in those plots,” he said in a news conference broadcast live on the English language channel Press TV.

On its website, Press TV reported the letter said a suspect who US prosecutors have identified as an Iranian military official is actually a member of the exiled Iranian rebel group Mujahideen Khalq Organisation (MKO).
