Leader of the Islamic Revolution Ayatollah Seyyed Ali Khamenei has condemned the US and Israeli spy agencies, CIA and Mossad, for the recent assassination of an Iranian nuclear scientist, Press TV reported.
"This cowardly [act of] terror, whose perpetrators and plotters will never dare to confess to their dirty and hideous crime or accept responsibility for it, has been carried out by the planning or support of CIA and Mossad [spy] services, like all other crimes of the network of international state terrorism," said Ayatollah Khamenei late on Thursday in a message of condolence on the death of Mostafa Ahmadi Roshan.
The assassination attempt shows that "the global arrogance spearheaded by the US and Zionism has reached a deadlock in confrontation with the determined, devout, and progressive nation of Islamic Iran," the leader added.
Ayatollah Khamenei went on to say that iran's rapid scientific progress is not dependent on individuals but is a "historic movement" and arises from the "invulnerable national resolve" of Iranians.
Insisting that the Iranian nation will continue on its path with determination, the leader pointed out that Iranians will not overlook the crime and never stop efforts to bring the perpetrators and those behind the assassination to justice.
On January 11, an unknown motorcyclist attached a magnetic bomb to the scientist's car near a college building of Allameh Tabatabaei University in Tehran. Ahmadi Roshan was immediately killed and his driver, who had sustained injuries, died a few hours later in hospital.
Ahmadi Roshan, a Sharif University of Technology chemical engineering graduate and the deputy director of marketing at iran's Natanz nuclear facility, was killed immediately and his driver, who had sustained injures, passed away a few hours later in hospital.
The latest terrorist attack comes as Iran has reached an agreement with the P5+1 -- Britain, China, France, Russia, and the United States plus Germany -- to hold negotiations in Turkey.
