Being an Iranian nuclear scientist is becoming a high hazard occupation.

(BBC News)- An Iranian scientist believed to have links to the country's nuclear programme has been shot dead outside his home in Tehran, Iranian media say.

Isna news agency named him as Daryoush Rezaei, 35, adding that his wife was wounded and rushed to hospital.

In 2010, nuclear scientist Massoud Ali Mohammadi was killed by a remote-controlled bomb in Tehran.

Iran blamed that attack on Israeli secret service Mossad. Israel has long warned about Iran's nuclear programme.

Some reports said the latest attack involved assailants on a motorcycle, who shot him in the neck in front of his house.
