KIEV, Ukraine (AP) — A Ukrainian official said a passenger plane carrying 295 people was shot down Thursday over a town in the east of the country, and Malaysia Airlines tweeted that it lost contact with one of its flights over Ukrainian airspace.
Anton Gerashenko, an adviser to Ukraine's interior minister, said on his Facebook page the plane was flying at an altitude of 10,000 meters (33,000 feet). He also said it was hit by a missile fired from a Buk launcher, which can fire missiles up to an altitude of 22,000 meters (72,000 feet).
The fate of the passengers wasn't immediately known.
Ukrainian President Petro Poroshenko said his country's armed forces didn't shoot at any airborne targets.
"We do not exclude that this plane was shot down, and we stress that the Armed Forces of Ukraine did not take action against any airborne targets," he said. "We are sure that those who are guilty in this tragedy will be held responsible."
Malaysia Airlines said on its Twitter feed that it "has lost contact of MH17 from Amsterdam. The last known position was over Ukrainian airspace." The plane's destination was Kuala Lumpur.
It was the second time that a Malaysia Airlines plane was lost in less than six months. Malaysia Airlines Flight 370 disappeared in March while en route from Kuala Lumpur to Beijing. It has not been found, but the search has been concentrated in the Indian Ocean far west of Australia.
The Donetsk region government said Thursday's plane crashed near a village called Grabovo, which it said is currently under the control of armed pro-Russian separatists. The region where the flight was lost has seen severe fighting between Ukrainian forces and pro-Russia separatist rebels in recent days.
A launcher similar to the Buk missile system was seen by Associated Press journalists near the eastern Ukrainian town of Snizhne earlier Thursday.
