Ban Ki-moon

UN Secretary General Ban Ki-moon condemned the killing of Iranian scientist Mostafa Ahmadi Roshan, saying terrorist actions are “not acceptable.”

The 32-year-old Ahmadi Roshan was killed on Wednesday along with his driver when an assailant attached a magnetic bomb onto his car on a street near Tehran University.

Reuters reports that UN spokesman Eduardo del Buey quoted the UN Secretary General as saying: "Any terrorist action or assassination of any people, whether scientist or civilian, is to be condemned. It is not acceptable. Human rights must be protected.”

Iran’s representative to the UN, Mohammad Khazai, had written to the UN chief, calling on him to condemn the assassination.

Iranian authorities blame Israel and the U.S. for the assassination. While the U.S. has denied any involvement in the attack, Israel has refused to comment.
