LISTEN ABOVE: Jerry Skinner spoke to Rachel Smalley

Investigators have told the families of the almost 300 people killed in July 2014, that a missile moved from Russia to eastern Ukraine was to blame.

They say the evidence is conclusive.

But Russia doesn't agree.

Jerry Skinner represents the widow of New Zealander Rob Ayley, among others, in the compensation bid.

He told Rachel Smalley it's time for Russia to come to the table.

"What happened today was a factual confirmation of their participation. We are inviting them to sit down and talk with us."

He said the new findings have great weight, and back their case.

"And it will submitted to court as further support to our allegations.We're hopeful that either the Russians will choose to respond or if they don't that the court will move ahead with the case without them."
