Tehran, Jan 12 (Inditop.com) Mercenaries of the US and Israel were behind the motorbike blast that killed an Iranian nuclear physicist Tuesday, Iran said.

Foreign Ministry spokesman Ramin Mihman-Parast termed the attack as an “inhuman action” intended to stop the technological progress in the country.

Masoud Ali-Mohammadi, a lecturer at the Tehran University and a staunch supporter of Islamic Revolution, was killed when a booby-trapped bomb exploded near his house in northern part of the city.

“Preliminary investigations indicated traces of the triangle of US-Israel and their lackeys in assassination of the professor,” Mihman-Parast was quoted as saying by IRNA news agency.

The spokesman said that the attack was against the country’s progress in the field of science and technology.

“Such inhuman actions will, instead, help mobilize the young and talented Iranians to speed up progress of their own country,” he added.
