Ukraines government and pro-Russian insurgents traded blame for the disaster, with comments attributed to a rebel commander suggesting his men may have downed Malaysia Airlines flight MH17 by mistake, believing it was a Ukrainian army transport plane.
Ukrainian President Petro Poroshenko believes a "terrorist act" was the cause of a Malaysian airlines passenger plane crashing on Thursday, his press secretary said. "Poroshenko thinks this of the plane that was brought down: it is not an incident, not a catastrophe, but a terrorist act," press secretary Svatoslav Tsegolko said.
US President Barack Obama vowed to assist Malaysia in finding out what caused the crash. Dutch Minister of Security and Justice Ivo Opstelten hosted a press conference shortly after the incident.
Malaysia Prime Minister Najib Razak was seen at the Kuala Lumpur International Airport around 1am, for meetings with officials before the press conference hours later.
Several airlines have diverted their flight to avoid the Ukraine airspace.
Singapore Airlines announced through its Twitter account that it will not use the airspace.
Russia's state-controlled Aeroflot will no longer fly over Ukraine, an official at the airline said, following the crash of a Malaysian passenger airliner in eastern Ukraine. Germany's largest airline Deutsche Lufthansa said on Thursday its planes would steer clear of east Ukrainian air space. "Lufthansa has decided to avoid the east Ukrainian air space by a wide margin with immediate effect," a company spokesman said.
France urged airline companies on Thursday to avoid Ukraine's airspace. Air France on Thursday it had decided to avoid east Ukrainian air space.
British Airways announced announced that only one daily flight to Kiev used the airspace, but that is far away from the crash site.
Dozens of severely mutilated corpses could be seen strewn in the wreckage of flight MH17 that crashed Thursday in rebel-held eastern Ukraine but there were no signs of survivors, an AFP reporter at the scene said.
Debris was spread out for kilometres and the tail of a passenger jet lay in a corn field with the Malaysian Airlines insignia on it while insurgent fighters and several fire trucks were seen nearby the crash site.
Eyewitnesses told AFP that the jet appeared to explode in mid-air before wreckage rained down over a large area.
Shocked local residents struggled to take in the scene of the carnage and said that remnants of the jet had been found in a village some 9km from the centre of the crash site.
"I had just gone to sleep at around 1600 (9pm Singapore time) when I heard an enormous bang," a 64-year-old resident, identified only as Katya, said. "It was like an earthquake." Her daughter Natalya, 36, said that she had fled to safety when the sound of the explosion rumbled overhead.
"I took my baby and went and hid in the basement," she said.
There was no sign of any rescue workers going through the gruesome site.
