Tehran | Iran's supreme leader demanded the “definitive punishment” of those behind the killing of a scientist who led Tehran's disbanded military nuclear program, as the country blamed Israel for a slaying that has raised tensions across the Middle East.

After years of being in the shadows, the image of Mohsen Fakhrizadeh suddenly was everywhere in Iranian media, as his widow spoke on state television and officials publicly demanded revenge on Israel for the scientist's slaying.
