U.S. intelligence officials say it appears Iran's anti-missile system shot down a Ukrainian plane and killed 176 people. Multiple media reports say the Boeing 737 plane bound for Kiev crash was an accident. The crash happened a few hours after Iran launched missiles to Iraq to attack bases that host U.S. troops. It's Russian built missile-defense system was likely active in case the U.S. decided to retaliate. Most of the people on board were either Iranian or Canadian. There were no survivors.
