Two Iranian missiles struck down a Ukrainian passenger jet, the New York Times reported on Tuesday. the newspaper posted verified security camera footage showing 2 missiles gliding through the sky before hitting their target. The missiles were fired 30 seconds apart and help explain a mystery as to why the plane's transponder was not working -- it was disabled by the first strike, before being hit by a second, the Times said. The blurry footage shows the plane on fire and circling back to Tehran's airport, the Times said. Minutes later, it exploded and crashed.
