If this is true, then their next target just got a lot harder to hit.

A scientist involved in Iran’s nuclear program died two weeks ago in mysterious circumstances said to be connected with the Mossad, the Sunday Times has reported.

According to the report, an American source hinted that the prize-winning scientist, Prof. Ardshir Hassanpour, 44, was assassinated by the Mossad.

His death was reported on January 21, six days afterwards. At the time, his death was attributed to gas poisoning.

The report first surfaced when announced by US-funded Iranian radio station, Radio Farda.

Hassanpour was said to have worked at the Isfahan nuclear technology center, in which uranium hexafluoride gas is produced.
