We demand explanation, not only from Russia but also from Ukraine!
It was a war zone, anyway, but are commercial planes allowed to fly above it?
At such height, the weapons used to shoot down the plane must be one of the most sophisticated. Who could have fired it?

I am shocked by reports that an MH plane crashed. We are launching an immediate investigation.
A passenger plane with 295 people on board has been shot down as it flew above eastern Ukraine, according to aviation sources.
The Boeing 777 was brought down by a Buk ground-to-air missile, an adviser to the Ukrainian interior ministry quoted by the news agency said.
The adviser said the 280 passengers and 15 crew members who were on the plane are all believed to have died.Ya Allah! What actually took place?
A spokesman for Malaysian Airlines, still reeling from the loss of flight MH370 in March, confirmed it had lost contact with flight MH17, which departed from Amsterdam at 12.14pm local time.
The flight disappeared from radar as it flew over Ukrainian airspace, the spokesman said.
Sky's Katie Stallard, in Moscow, said media reports suggest the plane came down in the Donetsk region, where there has been recent heavy fighting amid continuing tensions between Russia and Ukraine.
Data from Flightradar24 suggests the plane had just passed the city of Kremenchuk when it disappeared.
Several videos apparently filmed in the area, none of which Sky News has been able to independently verify, show plumes of thick, black smoke rising high into the air.
An aviation source told the Reuters news agency the wreckage of a burning aircraft had been found on the ground.
Aviation expert Major Charles Hayman told Sky News: "It's highly likely this aircraft was flying along a fault line between Russian and Ukrainian defences.
"It’s possible the Ukrainians flapped a bit, thought it was hostile and shot it down.
"Perhaps it was confusion at the Ukrainian air defence centre.
"It looks like someone failed to recognise this was a civilian plane and shot it down."
A spokesman for Boeing said it was aware of reports of MH17's disappearance, while a Foreign Office official added: "We're urgently working to establish what has happened."
