The United States has concluded the Malaysian airline was shot down, a senior U.S. official told CNN's Barbara Starr. One radar system saw a surface-to-air missile system turn on and track an aircraft right before the plane went down Thursday, according to the official. A second system saw a heat signature at the time the airliner was hit, the official said. 

The United States is analyzing the trajectory of the missile to try to learn where the attack came from.

- "We must and we will find out precisely what happened to this flight. No stone will be left unturned," Malaysian Prime Minister Najib Razak told reporters. He called for an international team to have full access to the crash site. "If it transpires that the plane was indeed shot down, we insist that the perpetrators must swiftly be brought to justice," he said.

- U.S. Vice President Joe Biden said Thursday that Ukraine's president accepted an offer of U.S. experts to investigate the crash of a Malaysia Airlines jetliner there, adding "they will be on their way rapidly to see if we can get to the bottom of this."

Malaysia Airlines jet crashes in Ukraine; official says 295 people 'shot down'

(CNN) -- A Malaysia Airlines passenger jet crashed in eastern Ukraine on Thursday, prompting swift accusations from Ukrainian officials that "terrorists" shot down the aircraft.

The Boeing 777 carrying 295 people went down near the town of Torez in the Donetsk region of eastern Ukraine, according to a Facebook post from a top Ukrainian official, as it flew at about 10,000 meters (nearly 33,000 feet) on the way from Amsterdam to Malaysia.

Anton Gerashchenko, adviser to the Ukrainian Interior Ministry, said in a Facebook post that "terrorists" fired on the plane operating a Buk surface-to-air missile system.

Ukrainian President Petro Poroshenko described the crash as a "terrorist action."

"We do not exclude that the plane was shot down and confirm that the Ukraine Armed Forces did not fire at any targets in the sky," Ukrainian President Petro Poroshenko said, according to his website.

The crash sent emergency crews scrambling to what witnesses described as a staggering scene.

"People said the plane kind of exploded in the air, and that everything rained down in bits and pieces, the plane itself, the people inside," said Noah Sneider, an American freelance journalist who interviewed witnesses at the scene.

Now, charred wreckage stretches for kilometers, he said. Stunned rescue workers and rebel fighters are combing the area, Sneider said, planting sticks with white cotton ribbons where they find bodies in the fields.

"As you walk through the fields, you see a man with his cracked iPhone sticking out of his pocket. You see sort of people's clothing everywhere. Most of it's kind of ripped off by the air. There's some suitcases and stuff in a pile by the road," Sneider said.

There are many bodies left to be found, he said, but night is falling, and people are trying to figure out what to do next.

Locals in the rural area trying to help were overwhelmed, he said. Firemen who rushed to put out the flames found they had a hose with holes in it, spraying water everywhere, he said.

"One man said to me, 'Nothing's happened in this village for 30 years, and now this,'" Sneider said.

Malaysia Airlines: We've lost contact with plane

Details are quickly pouring in about Thursday's crash which comes the same week that Ukrainian officials said a Russian fighter shot down a Ukrainian military transport plane while the aircraft was in Ukrainian airspace.

As news broke of the crash, Malaysia Airlines confirmed in a tweet that it lost contact with Flight 17 and that the jet's last known position was over Ukrainian airspace.

CNN's Richard Quest, an aviation expert, said that it would be "extremely unusual" for an airliner at 32,000 feet to be shot down. From the ground, one could simply look up and tell whether a plane was a commercial aircraft.

"It looks like a commercial aircraft, it squawks a commercial aircraft. So something is absolutely appalling that's gone on here," he said.

Reports are still coming in about who may have been on board and where they're from.

But Laurent Fabius, France's Minister of Foreign Affairs, confirmed to CNN that there were at least four French victims on the plane.

FlightRadar24 showed the plane disappearing near Kremenchuk, Ukraine.

Malaysian Prime Minister Najib Razak tweeted that an investigation will be launched immediately. "I am shocked by reports that an MH plane crashed," he posted.

And Ukrainian Prime Minister Arseniy Yatsenyuk ordered that a government commission investigate the crash, a statement from his office said.

Russian President Vladimir Putin "expressed deep condolences" to Malaysia's Prime Minister over the crash, a post Thursday on the Kremlin's website said. He "asked to pass the most sincere word of condolences and support to families and relatives of (the crash) victims," the post said.

Near the end of a phone call Thursday morning with President Obama, Putin noted to the President the early reports of a downed passenger jet near the Russia-Ukraine border, White House press secretary Josh Earnest said.

Obama directed his staff to be in touch with senior Ukrainian officials, Earnest said.

Later Thursday, Obama said the crash "looks like it may be a terrible tragedy" and he said efforts were underway to determine if any Americans were aboard.

Vice President Joe Biden, who was traveling in Detroit Thursday, talked on the phone with President Poroshenko, Earnest said, adding that Biden offered U.S. assistance to help determine why the crash occurred.

Poroshenko said he has expressed condolences to Netherlands Prime Minister Mark Rutte about the crash.

Russia-Ukraine dispute

The route the Malaysian plane was on, between Kuala Lumpur and the Netherlands, is a common one, CNN aviation safety consultant Mary Schiavo said Thursday. She said that the plane was flying over a troubled area and that close communication with air traffic controllers would be a key necessity.

Torez is in a rebel-held area.

In hostile or disputed areas, "any alteration from your course, and you can have a problem," Schiavo said.

Map: Approximate route of MH17

Tensions have been high between Ukraine and Russia since street protests forced former pro-Moscow President Viktor Yanukovych from power in February. Russia subsequently annexed Ukraine's southeastern Crimea region, and a pro-Russian separatist rebellion has been raging in Ukraine's eastern Luhansk and Donetsk regions.

Ukrainian forces have been struggling to quell the separatist unrest. Ukraine's government has accused Russia of allowing weapons and military equipment, including tanks, to cross the border illegally into the hands of pro-Russian separatists.

The Pentagon said Wednesday that Russia now has 12,000 troops on the border with Ukraine, as well as some heavy weapons. The troop numbers had fallen to about 1,000 previously from a high of an estimated 40,000 forces earlier this year.
