8 years ago, flight MH17 was shot from the sky. Now there are "strong indications" Putin approved the missile.

International prosecutors say they have found "strong indications" that Russian President Vladimir Putin approved the use of a Russian missile system that shot down Malaysia Airlines Flight 17 over Ukraine eight years ago. 

However, evidence of Putin's and other Russian officials' involvement was not conclusive enough to lead to a criminal conviction, they said, ending their probe for now.

"There are strong indications that the Russian president decided on supplying the BUK," the prosecutors said in a statement on Wednesday.

But prosecutor Digna van Boetzelaer told a news conference in The Hague the investigation had now "reached its limit".

"The findings are insufficient for the prosecution of new suspects," she said.

MH17 was shot down by a Russian BUK missile system as it flew over eastern Ukraine from Amsterdam to Kuala Lumpur on July 17, 2014, killing all 298 passengers and crew including 38 Australian residents and citizens.

The Kremlin, which has repeatedly denied any Russian state involvement in the past, did not immediately respond to a request for comment, AAP reports. 

The findings come after a Dutch court convicted two former Russian intelligence agents and a Ukrainian separatist leader of murder for helping arrange the Russian BUK missile system that was used to shoot the plane down, in November. 

The three men, who were tried in absentia, remain at large.

After the plane's destruction, Australia, the Netherlands, Belgium, Ukraine and Malaysia set up a joint investigation team to establish who was responsible and to assemble evidence for criminal prosecutions.

Prosecutors said on Wednesday they could not identify the specific soldiers responsible for operating the missile system, which came from Russia's 53rd brigade in Kursk. But they cited two phone intercepts in their evidence.

The first was a 2014 conversation between Russian officials in which one indicated Putin's approval was necessary before a request for equipment made by the separatists could be granted.

"It is not known whether the request explicitly mentions a BUK system. A little later, the heavier air defence systems are delivered, including the BUK that shoots down MH17," prosecutors said.

The other call was a 2017 conversation between Putin himself and the top pro-Russia politician in Ukraine's breakaway Luhansk province, in which they discussed the military situation and a prisoner exchange.

Andy Kraag, head of the Netherlands' National Criminal Investigation Department, said the case could be reactivated with new evidence.

"The next answers, they lie in Russia. And as long as there's no co-operation in Russia those answers will remain there," he said.

"Our door remains open."

Ukrainian Prosecutor General Andriy Kostin said the country would "seek to employ all the existing international legal mechanisms" to bring Putin to justice.

Australia and the Netherlands have said they hold Russia responsible for MH17's downing.
