Iranian Professor Mostafa Ahmadi Roshan (32 year) was killed Wednesday morning on a street in Tehran by a bomb placed on his Peugeot 405 car by two men are on a motorcycle. Death of the scientist, who worked in uranium enrichment center in Natanz seems an exact copy of similar murders that occurred in recent years in Iran. Iranian authorities were quick to accuse Israel and the U.S. that is behind the attack on Wednesday, wanting to destabilize the situation before the elections in Iran. Tehran charges are mere propaganda but anti-Zionist or assassinations are part of a US-Israeli campaign, extremely aggressive and effective attempts to sabotage Iran's nuclear capabilities to develop?
List of officials, researchers and scientists involved in Iran's nuclear program that Tehran had disappeared or been murdered began to become more and more, from 2007:
* Alireza Asgari, a former deputy defense minister, disappeared while visiting Turkey in 2006. It is believed to teach a foreign intelligence agencies.
* Hossein-Pour Ardeshir, a scientist working at the center of the Isfahan uranium imobagatire, died unexpectedly in 2007 at the age of 44 years. The official explanation was that "it suffocated with gas."
* Massoud Ali Mohammadi, and nuclear physics professor at the University of Tehran, was killed when a bomb exploded controlled remotely near his home in January 2010.
* Shahram Amir, a physicist who worked at the plant at Natanz, disappeared while he was on pilgrimage to Mecca, in May 2009. Scientist suddenly appeared in the United States, then returned to Iran in July 2010, where he disappeared again, probably arrested by authorities on charges of treason.
* Majid Shahriar, nuclear engineering faculty member of Shahid Beheshti University in Tehran, was killed on 29 November 2010, when two persons on a motorcycle attached to a magnetic bomb his car window. The Telegraph writes that this type of murder seems to have become "modus operandi" in the campaign to eliminate Iranian scientists.
* Fereydoun Abbasi, and professor at the University Shahid Besheshti he was wounded the same day, in a similar attack. Three months later, Abbas became head of the Iranian Atomic Energy Organization.
* Darioush Rezai-Nejad, who was studying for a master's degree in electronics from the University tous Khajeh-Nasir, was shot dead in Tehran in July 2011. According to some information, he was a graduate of the University of Malek-e-Ashtar, affiliated to the Ministry of Defense of Iran.
* General Hassan Tehrani Moghaddam, who headed the Iranian missile program, died in a powerful explosion that occurred at the military base of Amir Al-Momenin Bidganeh, near Karaj, west of the capital Tehran. The incident occurred on 12 November 2011.
Why Iranian scientists die?
No Israeli or American official has not confirmed or denied information about a possible campaign of sabotage against Iran's nuclear program.
And yet, who's killing Iranians? American and Israeli experts newspapers recently said that the Central Intelligence Agency (CIA) in the U.S. and Israeli secret service Mossad covert operations currently carried out "effective and aggressive" to remove the Iranians involved in Tehran's nuclear file. Roshan's death seems to make it part of the same campaign and the assassination of Iranian scientists, started after 2007.
The wave of assassinations was accompanied by several Iranian nuclear explosions produced (at least four last year) and the emergence of a new computer virus, Duque, which affected the computer systems of nuclear power. Duque is a more sophisticated version of Stuxnet worm, which affected the Iranian centrifuges in 2010. Information from several sources indicated as the source of Israeli hackers Stuxnet virus that computers disordered system of Iranian nuclear reactors in 2010. Duque virus appearance is put everything on account of Israeli experts: new virus code is based on the same source as Stuxnet.
Speaking a few days after the explosion which occurred at the military base of Amir Al-Momenin Bidganeh, near Karaj, west of the capital Tehran in November 2011, after which he died General Moghaddam, Israeli Defense Minister Ehud Barak, said, "may be more like it." And on Wednesday, hours after the assassination of Roshan, General Yoav Mordechai, the Israeli army spokesman, wrote on its Facebook page: "I do not know who to avenge Iranian scientist, but clearly I do not cry him. "
What experts say:
* Richard Silverstein, Tikun Olam blog author: Iranian nuclear explosions to have been part of war covered by Israel against Iran and the U.S. went along with their supporters of MEK (editor's note. People's Mojahedin of Iran), are within the country. Unit 8200 in the Israeli armed forces (IDF), which makes research on the draft cyber war, created Stuxnet, with the United States. George W. Bush gave Israel 300-400 million dollars in 2007 to engage in this campaign, the money that finances the project. Assassination of Iranian scientists was made by those in MEK, with Mossad.
* Manuela Paraipan, foreign policy analyst: certainty in this case (editor's note. Explosions at nuclear power plants) have only intelligence, and finally, some might have. I do not think it's accidents, although this is possible and probable. Tactics can be used to avoid conflict or to weaken as much as possible, the other camp, before an attack. Efforts are also in one direction and another. I hope come true first draft.
* Expert Michael Rubin of the American Enterprise Institute, told CNN that another explanation "plausible" is the involvement of Arab secret services: "The idea that many Americans have that Mossad is the most talented service information the Middle East is expired decades. " He says some information services in the Arab world "might have to recruit Shiites" in the region, most likely in Iraq to act against Iran's nuclear program.
How effective is anti-Iranian campaign?
Ll Telegraph quoted Mark Fitzpatrick, director of nonproliferation at the International Institute for Strategic Studies, said that Egypt attempts to obtain nuclear weapons in the '70s, was successfully derailed by the assassination of key figures involved in the atomic program.
Assassination of Egyptian scientists, put it at the expense of Israel, was "essential to prevent Egypt to develop its" nuclear program.
"Iran's program is advanced, so do not know if decapitation strategy will work," said Fitzpatrick. "But it is possible that this campaign, combined with other strategies - industrial sabotage and so-called accidental explosions of nuclear installations - has some effect in delaying the Iranian program", says expert.
According to reports, Iranian scientists morale has suffered from the wave of assassinations of their colleagues. Many of those involved in the nuclear program live under constant guard, as is the case of Mohsen Fakrizadeh, professor of physics and Revolutionary Guard officer.
In addition, scientists are subjected to strict supervision. Center at Natanz is not connected to the Internet, so the virus must have been introduced Stuxnet by an agent. After the appearance of viruses, Iran has strengthened its security procedures at nuclear installations.
