The Islamic Republic has previously accused Israel, the United States and Britain of plotting the killings to set back its uranium enrichment program, which Western powers suspect is being used to develop nuclear weapons capability.
Intelligence Minister Heydar Moslehi spread the blame to France and Germany, after days of hawkish rhetoric and missile tests by Tehran that helped push benchmark Brent crude oil prices above $100 for the first time since June.
"In these two networks (involved in the assassinations) we saw connections with the information services in Germany, France, Britain, Israel, the United States and regional intelligence agencies," the state news agency IRNA quoted Moslehi as saying. He did not name the other countries.
At least four scientists associated with Iran's nuclear program have been assassinated since 2010, most recently in January this year. Washington has denied any role in the killings, while Israel has declined to comment.
Iran denies Western accusations of a covert agenda to develop a nuclear weapon, insisting it wants to stockpile enriched uranium solely to generate more electricity for a rapid growing population and radio isotopes for medical treatment.
Talks between world powers and Iran to resolve the standoff have so far failed to secure a breakthrough.
Oliver Thraenert, head of the think-tank unit of the Zurich-based Center for Security Studies, said that by accusing Western states of involvement in the assassinations, Moslehi could be signaling his opposition to any deal with them on the nuclear issue.
"It might be the case that behind these allegations is an internal fight about whether Iran should seek a compromise with the Western countries," Thraenert said.
"If you accuse a nation like Germany or France of being behind these assassinations of Iranian nuclear scientists of course it is obvious that you cannot strike a deal with those countries," he said.
Away from the international stage, Iran's nuclear program has become a domestic political football, with hardliners criticizing rivals for allegedly capitulating to the West.
In a poll conducted by the Islamic Republic of Iran News Network (IRINN) earlier this week, more than two thirds of respondents opted for "the suspension of uranium enrichment in exchange for the gradual lifting of sanctions," in answer to the question: "Which way do you prefer to confront the unilateral sanctions of the West against Iran?"
Nearly 20 percent favored closing the Strait of Hormuz in retaliation and another 18 said Iran should resist the sanctions in order to safeguard its nuclear rights.
The number of respondents was not known. Analyzing the results, IRINN said the poll "by no means can reflect the views of all or even the majority of the revolutionary people of Iran".
A European Union ban on the import, purchase or shipping of Iranian oil took effect on July 1 as part of widening international sanctions aimed at prodding Tehran into curbing enrichment and opening up to UN nuclear inspections.
Toughened US sanctions on Iran took effect on June 28.

New York Times columnist Nick Kristof was in Iran last June and travelled around without government minders. He didn't feel any sense of anti-American resentments among ordinary people who are suffering tremendous economic pain around the country due to sanctions imposed by the West. He said that people do - for the most part - put the blame on their own regime for that. So it comes as no surpirse that many Iranians prefer "the suspension of uranium enrichment in exchange for the gradual lifting of sanctions,”
@Ali:
But I can spell
The nuclear-issue against Iran is lead by US (with Israel behind the scene) but then UK, Germany and France are friends of Iran's enemy and they work in team. We have seen this team work when 11 member group of British, Irish, French and German dressed as tourists and arrived on separate flights killed Hamas Leader Mahmud al-Mabhuh who was visiting Dubai.
After the assassination of their scientist Mostafa Ahmadi Roshan, Iran said it had evidence of CIA involvement in the killing. Washington went out of its way to deny the charge and an anonymous US official pointed the finger at Israel. Israel's Prime Minister Netanyahu was recorded saying "while it is the whole world's obligation to stop Iran, the responsibility falls first and foremost on Israel". Israel reaffirms Iran is an enemy and then the blame on US, Israel and its ally in Europe is I think well placed.
@harry
lol, your annalysis is worst than a 5 years old!
Reuters is owned by the Rothschild family, which is the most powerful jewish family in the world. They own the federal reserve as well as Reuters and AFP.
When was the last time you read something on Reuters and AFP which made Israel look like the bad guy? Answer: NEVER.
Well they can blame anyone and everyone. Seems they are a bit confused. One can only hope they attack either Isreal or the US and Iran will then no longer be a problem for the world.....realize of course they are not a problem for PAK but a new partner.
