A Malaysia Airlines passenger plane en route from Amsterdam to Kuala Lumpur, Malaysia, with 295 people onboard was apparently shot down Thursday over Ukraine.
The aircraft was hit by a missile fired form a Buk launcher, according to the adviser to Ukraine’s interior minister, and the The New York Times reports that military and intelligence analysts are working to pin down the missile’s point of origin.
U.S. President Barack Obama, Ukrainian President Petro Poroshenko and Malaysian Prime Minister Najib Razak have responded to the tragedy, promising to investigate.
Poignant images of the crash site show what’s left of the plane. In the photo above, people near the village of Grabovo inspect debris from the plane, which was reportedly flying at an altitude of 33,000 feet when it was shot.
Luggage aboard Flight MH17 survived the crash of the Boeing 777 aircraft, which was heading from Amsterdam to Malaysia’s federal capital, Kuala Lumpur.
After learning of the crash, Obama said the U.S. government’s “first priority” is to determine whether any Americans were onboard the flight. “It looks like it might be a terrible tragedy,” he said.
“I would like to note that we are calling this not an incident, not a catastrophe, but a terrorist act,” Poroshenko told the Dutch prime minister, Mark Rutte, in a phone call to express condolences, according to The New York Times.
The area where the flight was lost has seen severe fighting between Ukrainian forces and pro-Russia separatist rebels in recent days, reports the Associated Press.
