Boris leads calls to make Putin suffer for downing MH17

He added: “To do otherwise would be to deny the families the justice they seek for their loved ones.”

The US State Department echoed calls “to hold Russia to account”.

Spokeswoman Heather Nauert said: “It is time for Russia to acknowledge its role in the shooting down of MH17 and to cease its callous disinformation campaign.”

Yesterday Moscow continued to deny being involved in the plane’s destruction.

Its foreign minister Sergei Lavrov compared the findings of the international criminal investigators, who reported on Thursday, with earlier British claims that the poisoning of former spy Sergei Skripal and his daughter Yulia was Moscow’s work.

He said: “It looks much like the Skripal affair when they said that it was ‘highly likely’ done by Russians but Scotland Yard immediately said that the investigation is ongoing and will take some time.

“If our partners decided even in this case of a greatest human tragedy, the death of hundreds of people, to speculate on it for achieving their political goals, I leave it on their conscience.”

Flight MH17 was shot down over Ukrainian territory held by pro-Russian separatist forces as it flew from Amsterdam to Kuala Lumpur.

On board were 193 Dutch nationals, 43 Malaysians, 27 passengers from Australia and other victims from Indonesia, Belgium, Germany and the Philippines. Investigators from Australia Wreckage of the downed jet, part of the missile used on show this week, and Boris Johnson and Holland, among other countries, have presented evidence that the Buk missile used to bring down the plane came from the Russian 53rd Anti-Aircraft Brigade, based in the western Russian city of Kursk.

They concluded that “all the vehicles in a convoy carrying the missile were part of the Russian armed forces”. Moscow refused to cooperate with the investigation despite international legal requests. It insisted none of its missile launchers had entered Ukraine, despite photographic evidence from prosecutors.

But Dutch prime minister Mark Rutte said investigators have “irrefutably established that Russia can be held responsible for their part in downing MH17”. He added that the Putin regime was “responsible for deploying” the missile launcher used to shoot down the airliner.

Mr Rutte said: “The finger points to one specific country. We are holding Russia responsible for their role.”

Lawyers are now pouring over the findings of the official report into the attack and are expected to prepare a case before an international court.
