The crash of Malaysia Airlines Flight MH17 was a horrible tragedy on a global level.
President Barack Obama spoke Friday morning about the crash, accentuating the fact that the entire world was affected.
The President confirmed that at least one US citizen - Quinn Lucas Schansman - was lost in the crash.
Obama also revealed the current belief by American intelligence that Russian-backed separatists in the Ukraine were responsible for the missile that brought down the flight.
