Iran blast kills nuclear scientist

ROUGH CUT - NO REPORTER NARRATION
An Iranian nuclear scientist was killed by a bomb placed on his car on Wednesday in an attack Tehran's deputy governor blamed on Israel, raising the diplomatic temperature in a stand-off with the West over Iran's nuclear programme.
The bombing, which a city official said was similar to attacks a year ago on nuclear scientists in Iran, came as the United States sought to persuade a sceptical China to help efforts to toughen sanctions against Iran.
Iran's semi-official Fars news agency said the victim was a "nuclear scientist" who "supervised a department at Natanz Uranium Enrichment Facility".
