Three Russians and one Ukrainian have been named as murder suspects in the downing of the MH17 flight which killed 298 passengers - including a Leeds University student.
Richard Mayne, 20, was a Leeds University student on the flight from Amsterdam to Kuala Lumpur in 2014.
Dutch National Police chief Wilbert Paulissen identified Russians Igor Girkin, Sergei Dubinsky and Oleg Pulatov, along with Ukrainian Leonid Kharchenko, as suspects in the downing of the plane, and announced that their trial would start in March 2020.
All passengers and crew on board the flight from Amsterdam to Kuala Lumpur were killed on July 17 2014, when a missile shattered the Boeing 777 in midair sending debris and bodies raining down onto farms and fields of sunflowers.
One of the named murder suspects denied Ukrainian separatists shot down the plane.
Girkin told The Associated Press by phone on Wednesday that "the insurgents did not shoot it down".
An international investigation team looking into the plane crash has blamed it on a Russian missile that was shot from separatist-held territory.
Girkin, a Russian national, was a military chief of the Russia-backed rebels in the area at the time and was named by the investigators as one of the key suspects.
The international team investigating the downing of the flight will not ask Russia and Ukraine to extradite the four suspects.
Prosecutor Fred Westerbeke said that the team realises that the constitutions of both countries prohibit that.
"In the short term we will ask Russia to hand the summons to the suspects who are in the Russian Federation," he said.
