UNITED NATIONS - UN Secretary-General Ban Ki-moon said on Friday any killing like that of an Iranian nuclear scientist in Tehran earlier this week was to be condemned, a UN spokesman said.
Mostafa Ahmadi-Roshan, 32, was killed by a motorbike hitman who put a magnetic bomb on his car on a street near a Tehran university during the morning rush hour on Wednesday.
Iran, at odds with Western governments over its nuclear program, has accused US and Israeli agents of being behind the killing.
"Any terrorist action or assassination of any people, whether scientist or civilian, is to be condemned. It is not acceptable. Human rights must be protected," UN spokesman Eduardo del Buey quoted Ban as saying.
He said the UN chief was speaking to media accompanying him on a trip to Lebanon.
