Iran: Scientist Connected to Tehran's Nuclear Program Killed

An Iranian nuclear scientist was killed Jan. 11 in Tehran when an explosive device attached to his vehicle detonated. Mostafa Ahmadi-Roshan, who allegedly supervised a department at Iran's primary uranium enrichment complex, Natanz, was the fifth Iranian scientist connected to the nuclear program killed in the past five years. Given the tactics and target set, the attacks likely were carried out by local actors with foreign sponsorship. Besides continuing a trend, Ahmadi-Roshan's death also revealed that Iran could be pursuing a second method of uranium enrichment.
