A Malaysian airliner reportedly with 295 people on board has crashed in Ukraine near the Russian border, on a flight from Amsterdam to Kuala Lumpur.

Malaysia Airlines said it had lost contact with Flight MH17 from Amsterdam. The last known position was over Ukraine, it said in a tweet.

An aviation source in Moscow told Reuters the plane had been found burning on the ground in east Ukraine.

It had failed to enter Russian airspace, the source said.

The UK Foreign Office said it was aware of the reports of the crash and was "urgently working to establish what has happened".
