KIEV, Ukraine (AP) - UPDATE 5:50pm
A U.S. official says that American intelligence authorities now believe a surface-to-air missile took down the Malaysian passenger plane as it flew over eastern Ukraine Thursday.
The official says the U.S. is still working to determine additional details about the crash, including who fired the missile and whether it came from the Russian or Ukraine side of the border. The official was not authorized to discuss the matter publicly so spoke on condition of anonymity.
The U.S. has sophisticated technologies that can detect missile launches, including the identification of heat from the rocket engine.
The plane was carrying 295 people. The Ukraine government and pro-Russian separatists who are fighting in that region have both denied responsibility for the strike.

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).
An Associated Press journalist has counted at least 22 bodies at the plane wreckage site in eastern Ukraine involving a Malaysia Airlines commercial flight.
The plane appeared to have broken up before impact and the wreck is scattered over a wide area in the eastern Ukraine village of Grabovo.
The field around the burning wreck was strewn with body parts and the belongings of the passengers Thursday.
The Kremlin says Russian President Vladimir Putin and President Barack Obama have discussed the Malaysia Airlines plane incident over eastern Ukraine.
The Kremlin website published a statement late Thursday that says "the Russian leader informed the U.S. president of the report from air traffic controllers that the Malaysian plane had crashed on Ukrainian territory, which had arrived immediately before the phone call."
The statement gave no further details about what the leaders discussed with regard to the plane crash. The rest of the phone call was dedicated to the general situation in eastern Ukraine, and recent U.S. sanctions against Russian individuals and companies.
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."
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.
Separatist rebels in the eastern Ukrainian city of Donetsk have denied that they are responsible for shooting down a Malaysia Airlines passenger plane.
Andrei Purgin, deputy prime minister for the rebels, told The Associated Press the plane must have been shot down by Ukrainian government troops. He gave no proof for his statement, and Ukraine earlier denied shooting at any airborne targets.
A launcher similar to the Buk missile system was seen by Associated Press journalists near the eastern Ukrainian town of Snizhne earlier Thursday.
On Wednesday evening, a Ukrainian fighter jet was shot down by an air-to-air missile from a Russian plane, Ukrainian authorities said Thursday, adding to what Kiev says is mounting evidence that Moscow is directly supporting the separatist insurgents in eastern Ukraine. Security Council spokesman Andrei Lysenko said the pilot of the Sukhoi-25 jet hit by the air-to-air missile was forced to bail after his jet was shot down.
Pro-Russia rebels, meanwhile, claimed responsibility for strikes Wednesday on two Ukrainian Sukhoi-25 jets. The Ukrainian Defense Ministry said the second jet was hit by a portable surface-to-air missile, but added the pilot was unscathed and managed to land his plane safely
Moscow denies Western charges that is supporting the separatists or sowing unrest in its neighbor. The Russian Defense Ministry couldn't be reached for comment Thursday about the Ukrainian jet and Russia's foreign ministry didn't respond to multiple requests for comment.
Earlier this week, Ukraine said a military transport plane was shot down Monday by a missile fired from Russian territory.
The Malaysia Airlines plane is a Boeing 777-200ER, which was delivered to Malaysia Airlines on July 30, 1997, according to Flightglobal's Ascend Online Fleets, which sells and tracks information about aircraft. It has more than 43,000 hours of flight time and 6,950 takeoffs and landings.
If the plane was shot down, it would be the fourth commercial airliner to face such a fate. The previous three were:
— April 20, 1978: Korean Airlines Flight 902, which diverted from its planned course on a flight from Paris to Seoul and strayed over the Soviet Union. After being fired upon by an interceptor aircraft, the crew made a forced landing at night on the surface of a frozen lake. Two of the 97 passengers were killed by the hostile fire.
— Sept. 1, 1983: Korean Air Lines Flight 007 shot down by at least one Soviet air-to-air missile after the 747 had strayed into Soviet airspace. All 240 passengers and 29 crew were killed.
— July 3, 1988: Iran Air Flight 655 Aircraft was shot down by a surface to air missile from the American naval vessel U.S.S. Vincennes. All 16 crew and 274 passengers were killed.
