Families of murdered Iranian nuclear scientists are suing Britain, Israel and the US, accusing them of being behind the killings.
Rahim Roshan, father of Mostafa Roshan, director of the Natanz uranium enrichment facility, said the families have demanded Iran's judiciary pursue their complaint through international bodies.
"We've filed an indictment against the Zionist regime and the arrogant powers," Mr Roshan said.
Iran has blamed Israel's Mossad as well as the CIA and MI6 for the assassinations, which it says are part of a covert campaign to sabotage its nuclear programme. The US and Britain have denied involvement. Israel has not commented.Reuse content
