According toCBS News, U.S. satellites detected two surface-to-air missile launches that occurred shortly before the plane exploded. Missile components were apparently found near the location of the crash, a source who was inside an intelligence briefing told CBS News. The crash occurred just hours after Iran hadlaunched missiles at two military basesin Iraq that house U.S. troops.
Sources toldNewsweekthat Iran’s anti-aircraft missile systems were likely active after their attack on the military bases in Iraq.
CNNreported that Iranian troops may have mistakenly believed they were under attack in thetense hoursfollowing their strike on the military bases. (Iran’s strike came after PresidentDonald Trumpordered an airstrikein Iraq that killed the commander of Iran’s Quds Force, Major General Qassem Soleimani.)
According to CBS News, Iran has refuted the allegations.
The Department of Defense did not immediately respond to PEOPLE’s request for comment.
