Iranians attend a rally commemorating the 37th anniversary of the Islamic revolution, under a Shahed-129 Iranian drone , displayed by armed forces, in Tehran, Iran, Thursday, Feb. 11, 2016. Shahed, which means "witness" in both Farsi and Arabic, is a name of a family of drones produced by Iran. The Shahed-129 resembles the Israeli-built, V-tailed Elbit Systems Hermes 450, according to IHS Jane's Defence Weekly, which suggests it may have been reverse-engineered from a downed drone. The nationwide rallies commemorate Feb. 11, 1979, when followers of Ayatollah Khomeini ousted U.S.-backed Shah Mohammad Reza Pahlavi. (AP Photo/Ebrahim Noroozi)
