The statement by the G7 ministers came on the eve of a summit between US President Donald Trump and his Russian counterpart Vladimir Putin, but also just before the anniversary of the July 17, 2014 air disaster which killed all 298 crew and passengers when the airliner was shot down.
"That passenger flight MH17 was shot out of the sky and 298 innocent people were murdered is an irrefutable fact", Maslin wrote. "That this killed our 3 handsome children and their grandfather, and destroyed our life and many other lives in the process, is an irrefutable fact", Maslin wrote.

Mo, 12, Evie, 10 and Otis, eight were returning from a holiday with their grandfather when their plane was shot down.

Mr Trump delivered a widely condemned performance alongside Mr Putin following the two leaders' first summit, in which he sided with the Russians against his own intelligence services over the issue of Russian interference with the U.S. election.
Transport Minister Anthony Loke said on the fourth anniversary of the tragedy yesterday that Malaysia will not relent in its pursuit of justice for the victims of the deadly attack.
"That this killed our three handsome children and their grandfather, and destroyed our life and many other lives in the process, is an irrefutable fact".
"That this happened 4 years ago today... is an irrefutable fact".
Mr Maslin said that it's "not anger that I feel towards the two of you, its something much, much worse".
Maslin said both Trump and Putin lacked any empathy for the rest of humanity and clearly do not have any appreciation of love for their fellow man.
