Iran Cracks Down as Protests Over Downing of Airliner Grow

We first learned that it was a missile that took down a Ukrainian airliner over Iran because of this video showing the moment of impact. All 176 people on board were killed. To find out what happened to Flight 752 after it left Tehran airport on Jan. 8, we collected flight data, analyzed witness videos and images of the crash site, to paint the clearest picture yet of that disastrous seven-minute flight. We'll walk you through the evidence, minute by minute, from the plane's takeoff to the moment it crashed. Iran has just launched ballistic missiles at U.S. military targets in Iraq in retaliation for an American drone strike that killed Iranian military leader Qassim Suleimani.
