Iran has accused US intelligence agency CIA of being involved in the assassination of Iranian nuclear official.
In a protest letter to the US government, the Iranian foreign ministry said the Central Intelligence Agency (CIA) was behind the recent terrorist attack leading to Iranian nuclear official's assassination, Xinhua quoted Tehran Times as saying.
Mostafa Ahmadi-Roshan,32, the deputy chief of the commercial section of Iran's Natanz nuclear enrichment site, was killed in a car bomb attack in northern Tehran last Wednesday.
The letter addressed to the US government, read, "according to authentic documents and reliable information, the assassination plot was directed, supported, and planned by the CIA and was carried out with the direct involvement of the agents affiliated with this agency, and the (US) government was directly responsible for it and should be answerable based on international regulations," the Iranian daily reported.
The protest note was delivered to Swiss Ambassador to Tehran Livia Leu Agosti Jan 14. The Swiss embassy in Tehran represents the US interests in Iran since Tehran and Washington severed diplomatic relations in 1980.
Iran's foreign ministry also said that it had also sent another protest note to the British government over the assassination of the Iranian nuclear scientist Majid Shahriari, in November 2010, Tehran Times reported.
