ROTTERDAM, Netherlands - Dutch prosecutors said Tuesday they have identified many "persons of interest" in their probe into the shooting down of flight MH17 over Ukraine, but no definite suspects.
"We have a large group of people that we're at this stage branding 'persons of interest' in whom we have an above average interest," Dutch chief prosecutor Fred Westerbeke told a press briefing in Rotterdam.
"But we've not yet taken the formal step of making them suspects," he told journalists, almost a year after the Malaysia Airlines flight was downed over war-torn Ukraine, killing all 298 on board, the majority of them Dutch.
The Netherlands has been tasked with leading the investigation into the cause of the disaster and identifying the victims of the July 17, 2014 crash. It is also in charge of the criminal prosecution of those responsible.
Westerbeke said although "great steps" were being made in the criminal probe to find those responsible, a dossier to take to trial would not be ready "at least before the end of the year."
Kiev and the West claim that the plane was shot down by pro-Russian separatists using a BUK surface-to-air missile supplied by Moscow.
Shortly after the crash, the UN Security Council adopted Resolution 2166 which demanded that those responsible "be held to account and that all states co-operate fully with efforts to establish accountability."
The Netherlands has floated the idea of a UN-backed tribunal, an idea to which veto-wielding Security Council member Russia is opposed.
Dutch Foreign Minister Bert Koenders however on Monday told the Nieuwsuur news programme that "it would be unwise pinning it (the prosecution) on one option only."
"I am discussing it with... many countries to see what the most effective option could be to try the guilty parties," Koenders said.
Russia last week rejected calls for the establishment of a UN tribunal calling untimely and "counterproductive."
Westerbeke said Dutch prosecutors favoured a court "in which we have the broadest international support for a prosecution" whether a UN tribunal or a Dutch court.
"We don't know how the case will eventually be tried," Westerbeke said, but it has to conform to Dutch norms and to those of other countries wanting to use the same file for prosecution.
Westerbeke also mooted a possible trial in absentia "as a last resort" should the perpetrators of the crime not be found or if a country refused to have them extradited.
The Boeing 777 was flying from Amsterdam to Kuala Lumpur when it was shot down.
In an initial report published last year, the Dutch Safety Board said the plane had been hit by numerous "high-energy objects".
A final report is due later this year.
