“The International Atomic Energy Agency (IAEA) must be trusted by nations because nations and governments give their documents to the agency," said speaker of the Majlis (parliament) National Security and Foreign Policy Committee Kazem Jalali on Wednesday.
“How the enemies of [the Islamic] establishment have obtained the names and information of our country's elite is a question we would like to know the answer to,” he added.
Jalali stressed that the IAEA, international community and the UN nuclear agency's member states using their membership against the Islamic Republic must be held accountable for their actions.
The lawmaker said the resemblance of the Wednesday assassination and other Zionist-American killings indicate that the “principle of assassination has been institutionalized in the American system and Zionist regime.”
“Assassinations like what happened in Tehran this morning lack operational value as such assassinations are called blind [acts of terror] which prove the maximum frustration of the enemies because they have not been able to weaken the [Iranian] nation's resolve and therefore resort to any shameful measure,” Jalali said.
Ahmadi Roshan was a Sharif University of Technology chemical engineering graduate and served as the deputy director of marketing at Iran's Natanz nuclear facility.
On Wednesday morning, an unknown motorcyclist attached a sticky bomb to Ahmadi Roshan's car near Allameh Tabatabaei University in Tehran.
Ahmadi Roshan was immediately killed as the result of explosion, 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.
The US, Israel and their allies accuse Iran of pursuing a military nuclear program and have used this allegation as a pretext to sway the UNSC to impose four rounds of sanctions on Iran.
Based on these accusations, they have also repeatedly threatened Tehran with the "option" of a military strike.
This is while in November 2011, some of the US presidential hopefuls called for conducting covert operations ranging from assassinating Iranian nuclear scientists to launching a military strike on Iran as well as sabotaging Tehran's nuclear program.
The calls for assassinations are not idle threats as a number of Iranian scientists have been assassinated over the past few years. Professor Majid Shahriari and Professor Masoud Ali-Mohammadi are among the victims of these acts of terror.
On November 29, 2010, Shahriari and Fereydoun Abbasi were targeted by terrorist attacks; Shahriari was killed immediately and Dr. Abbasi, the current director of Iran's Atomic Energy Organization, only sustained injuries.
Iran says as the UN Resolution 1747, adopted against Tehran in March 2007, cited Abbasi's name as a "nuclear scientist," the perpetrators were in a position to trace their victim.
According to reports, Ahmadi Roshan had recently met International Atomic Energy Agency (IAEA) inspectors, a fact which indicates that the IAEA has leaked information about Iran's nuclear facilities and scientists.
