The Dutch government is to take Russia to the European Court of Human Rights for its alleged role in the shooting down of Malaysia Airlines Flight 17 over eastern Ukraine six years ago.
The move is intended to support individual cases being brought to the European court by relatives of some of the 298 people who were killed.
A Buk surface-to-air missile fired from territory controlled by pro-Moscow Ukrainian rebels blew the Amsterdam to Kuala Lumpur flight out of the sky on July 17, 2014.
"Achieving justice for 298 victims of the downing of flight MH17 is and will remain the government's highest priority," foreign minister Stef Blok said. "By taking this step we are moving closer to this goal."
By launching the case against Russia, the Dutch authorities can share "all available and relevant information about the downing of Flight MH17" with the Strasbourg-based European court so it can be considered in individual relatives' cases.
"As a government, we have information, evidence, that leads us to the conclusion of the involvement of the Russian Federation," Mr Blok said.
"The relatives themselves do not have all this information so we can help them by starting this procedure."
Moscow has repeatedly denied involvement in the downing of the Boeing 777.
An international team of prosecutors investigating the case has, however, charged three Russians and a Ukrainian with involvement in bringing down the plane and the murder of all on board.
The men are on trial in a Dutch court, although none have been extradited to the Netherlands to face justice.
Mr Blok said much of the evidence which will go before the human rights court is also part of the criminal case.
Prosecutors say they have evidence the missile that blew MH17 out of the sky was transported into Ukraine from a Russian military base and the mobile launcher was later returned to Russia.
Konstantin Kosachev, head of the foreign affairs committee in the upper house of Russia's parliament, called the Dutch move "a strange initiative from every aspect".
He said: "The investigation isn't over yet, there have been no court verdicts on the national level yet and, finally, what does the European Court for Human Rights have to do with it?"
Yesterday's move is the latest legal manoeuvre by the Dutch government, which has long vowed to secure justice for victims and their loved ones.
