Update on the Tehran Attacks Targeting Scientists

In light of new details, the attacks against the two scientists in the Iranian capital Nov. 29 look fairly sophisticated and perhaps more damaging to Tehran than the similar attack against scientist Massoud Ali-Mohammadi in January. The perpetrators behind the Nov. 29 attack were able to identify and track two seemingly high-profile scientists involved in Iran's nuclear program and constructed explosive devices that, according to images from the scene of one of the attacks, specifically targeted the scientists using shaped charges and projectiles. Furthermore, the attackers had the manpower and coordination to target both scientists simultaneously.
