Reports: Bomb Blast Kills Iranian Nuclear Scientist

Iran says a “terrorist bomb blast” has killed an Iranian nuclear scientist. Iran blames the U.S. and Israel for the blast, the New York Times reports:

The scientist was identified as Mostafa Ahmadi Roshan, 32, a professor at Tehran’s technical university, and a department supervisor at the Natanz uranium enrichment facility — one of two known sites where Western leaders suspect Iranian scientists are advancing toward the creation of a nuclear weapon.
