The wife of an assassinated Iranian nuclear scientist said that her husband’s “ultimate goal was the annihilation of Israel.”

Fatemeh Bolouri Kashani, the wife of Mostafa Ahmadi Roshan, told the Fars News Agency in an interview published Tuesday that her husband was highly supportive of individuals that fought for the rights of the Palestinians against Israel.

Roshan, a chemistry professor and deputy director of commerce at Iran’s Natanz enrichment facility, was killed by a car bomb in early January. 

He is one of at least four Iranian nuclear scientists to have been killed in anonymous attacks since January 2010. Iranian officials have blamed the killings on operatives of Israel’s Mossad intelligence agency and America’s Central Intelligence Agency.
