(CNN) — 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.
In other developments:
– “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.”
Biden said the plane was apparently shot down, adding “not an accident, blown out of the sky.”
– Vice President of Malaysia Airlines Europe Huib Gorter told reporters that the 15 crew members on Malaysia Airlines Flight 17 were all Malaysian nationals. He gave a breakdown of the known nationalities of the 280 passengers: 154 were Dutch, 27 were Australians, 23 were Malaysians, 11 were Indonesian, six were from the United Kingdom, four were from Germany; four were from Belgium, three were from the Philippines and one was Canadian. Authorities were still trying to determine the nationalities of the other passengers.
(CNN) — A Malaysia Airlines passenger jet crashed in eastern Ukraine on Thursday, prompting a Ukrainian official to say that the flight carrying 295 people had been shot down.
The Boeing 777 was “shot down” by “terrorists” operating a Buk surface-to-air missile system, according to a Facebook post from Anton Gerashchenko, adviser to the Ukrainian Interior Ministry.
The plane went down near the town on Torez in the Donetsk region of eastern Ukraine, according to the post, as it flew at about 10,000 meters (32,000 feet).
“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.
He also said he has expressed condolences to Netherlands Prime Minister Mark Rutte about Flight 17, which was headed from Amsterdam to Malaysia. He said he invites Dutch experts to participate in the investigation of the crash, emphasizing that he does not call it an “incident” or a “catastrophe,” but a “terrorist action.”
Details of the incident are quickly pouring in during the same week that Ukrainian officials said a Russian fighter shot down a Ukrainian military transport plane while the aircraft was in Ukrainian airspace.
Malaysia Airlines has confirmed that it lost contact with Flight 17 and that the jet’s last known position was over Ukrainian airspace, the airline said on Twitter.
Reacting to the breaking story, 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.
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 has 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.
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.
In hostile or disputed areas, “any alteration from your course, and you can have a problem,” she said.
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.
On Thursday, CNN reported that Ukrainian officials said a Russian fighter shot down a Ukrainian jet Wednesday as the jet flew in Ukrainian airspace.
Tensions are high over that incident, separate from the breaking news of the Malaysian flight Thursday.
Three months ago, the U.S. Federal Aviation Administration prohibited U.S. airlines from flying in areas not far from where Flight 17 reportedly crashed Thursday. “Due to the potential for conflicting air traffic control instructions from Ukrainian and Russian authorities and for the related potential misidentification of civil aircraft, United States flight operations are prohibited until further notice in the airspace over Crimea, the Black Sea and the Sea of Azov,” the FAA said in April. Thursday’s plane crash reportedly was in eastern Ukraine, scores of miles north-northeast of the Sea of Azov.
On Thursday, French transportation official Frederic Cuvillier ordered that French airlines avoid Ukrainian airspace until the cause of Thursday’s Malaysia Airlines crash is known, the French Transportation Ministry said in a news release.
On top of that, the report of a downed Malaysian flight marks the second time this year that Malaysia Airlines has faced an incident involving a downed plane.
On March 8, Malaysia Airlines Flight 370 disappeared. That plane had 239 people on board. Searchers have found no trace of 370 or its passengers, despite extensive search efforts.
Flight 370 probably flew into the southern Indian Ocean on autopilot with an unresponsive crew, Australian authorities said last month.
During the early phase of the search for Flight 370, aircraft and ships scoured vast stretches of the surface of the southern Indian Ocean but found no debris.
Pings initially thought to be from the missing plane’s flight recorders led to a concentrated underwater search that turned up nothing.
A new underwater search, farther south, will be broadly in an area where planes and vessels had already looked for debris on the surface of the water. It is expected to begin in August.
