Families of murdered Iranian nuclear scientists are suing Britain, Israel, and the US accusing them of being behind the killings.

Rahim Ahmadi Roshan, father of Mostafa Ahmadi Roshan, a chemistry expert and a director of the Natanz uranium enrichment facility in central Iran, said that the families have demanded Iran's judiciary pursue their complaint through international bodies and bring those behind the killings to justice.

"We've filed an indictment against the Zionist regime and the arrogant powers," Mr Roshan said."(The judiciary) is to pursue this case with the relevant international bodies."

Iran's state television broadcast purported confessions earlier this month by 14 suspects in connection with the killing of five nuclear scientists since 2010.

The TV also showed pictures from a military garrison it said was a training camp outside Tel Aviv in Israel. It said the suspects took courses there, including how to place magnetic bombs on cars - the method used to kill the scientists.

The suspects also said they received training in Israel.

Iran says the attacks are part of a covert campaign by Israel and the West to sabotage its nuclear programme, which many suspect is aimed at producing nuclear weapons. Iran denies that.

Iran has blamed Israel's Mossad as well as the CIA and Britain's MI6 for the assassinations, with support from some of Iran's neighbours. The US and Britain have denied involvement. Israel has not commented.

"Through this complaint, we declare to the world that actions of arrogant governments, led by the US, Britain and the occupying Zionist regime, in assassinating nuclear scientists and elites is against human principles," said Mansoureh Karami, wife of murdered Tehran University physics professor Masoud Ali Mohammadi.

In May, Iran hanged Majid Jamali Fashi, 24, for the 2010 killing of Ali Mohammadi. Fashi, who said in televised confessions that he was recruited by Mossad, was convicted last August.
