Iran: U.S. Helped Kill Our Scientist

Iran claims to have proof that the United States was behind this week's murder of one of their leading nuclear scientists.

The IRNA state news agency said Saturday that Iran’s Foreign Ministry has sent a diplomatic letter to the U.S. saying that it has “evidence and reliable information” that the CIA provided “guidance, support and planning” to assassins “directly involved” in Roshan’s killing. The U.S. has denied any role in the assassination. Iran delivered the letter to the Swiss Embassy in Tehran, which looks after U.S. interests in the country. Iran and the U.S. have had no diplomatic relations since the 1979 Islamic Revolution.
