Iran has time and again lashed out at the United States and European countries for harboring the anti-Iran Mujahedin-e-Khalq Organization terrorist group, saying the MKO supporters have the blood of thousands of Iranians on their hands.
The MKO has carried out numerous terrorist attacks against Iranian civilians and government officials since victory of the Islamic Revolution in Iran in 1979. Out of the nearly 17,000 Iranians killed in terrorist attacks over the past four decades, about 12000 have fallen victim to MKO's acts of terror.
Washington and the European Union have removed the MKO from their lists of terrorist organizations.
The anti-Iran terrorists enjoy freedom of activity in the US and Europe, and even hold meetings with American and EU officials.
