(Adds details from case)
AMSTERDAM, June 14 (Reuters) - Investigators will next week announce criminal proceedings against suspects in the downing of Malaysia Airlines Flight MH17 five years ago, allegedly by pro-Russian separatists, two leading Dutch broadcasters reported on Friday.
MH17 was shot out of the sky over territory held by separatists in eastern Ukraine as it flew from Amsterdam to the Malaysian capital Kuala Lumpur, killing all 298 people on board.
About two-thirds of the passengers were Dutch.
Dutch prosecutors said on Friday a multi-national investigation team would present its latest findings to media and families on June 19. A spokesman for the national Dutch prosecution service declined to specify what would be announced.
Citing anonymous sources, broadcaster RTL reported that the public prosecution service had decided to launch a case against several MH17 suspects.
National public broadcaster NOS also reported that criminal proceedings will be announced against individual suspects.
No suspects were named in the reports.
The Joint Investigation Team, which seeks to try the suspects under Dutch law, has said the missile system came from the Russian 53rd Anti-Aircraft Brigade, based in the western Russian city of Kursk.
Investigators had said their next step would be to identify individual culprits and to attempt to put them on trial.
Dutch officials have said Russia has refused to cooperate.
Russia is not expected to surrender any potential suspects who may be on its territory and authorities have said individuals could be tried in absentia.
The Joint Investigation Team was formed in 2014 by Australia, Belgium, Malaysia, the Netherlands and Ukraine to investigate collaboratively.
The Netherlands and Australia, which lost 38 people, hold Russia legally responsible. Moscow denies all involvement and maintains that it does not support, financially or with equipment, pro-Russian rebels fighting Ukrainian government troops.
