NIEUWEGEIN, Netherlands—Dutch prosecutors investigating the crash of Malaysia Airlines Flight 17 more than two years ago are set to deliver their initial findings Wednesday on the downing of the jetliner.

Dutch prosecutor Fred Westerbeke is leading the international criminal probe into the 2014 crash that killed all 298 people on board. The report is expected to address issues not covered in the air-safety probe, also led by the Netherlands, which last year determined a sophisticated Russian anti-aircraft missile brought down the Boeing 777 plane.

Dutch officials have said that in Wednesday's report they would provide more information about the missile that struck the passenger plane and the exact location from where the weapon was fired. But they won't shed more light on the identity of the suspected perpetrators. That part of the probe could take more time, they have said.

The jetliner operated by Malaysia Airlines was flying from Amsterdam to Kuala Lumpur when it plunged out of the sky over eastern Ukraine. Pro-Russian separatists and Ukrainian troops were fighting for control of the region at the time. Most of the fatalities were Dutch.

Ukraine has accused Russian-backed militants operating in the area where the missile was launched. Russia and the rebels it supports have said Ukrainian forces were responsible.

Russia vetoed a United Nations Security Council resolution that would have established an international criminal tribunal to investigate the downing of the plane.

The Dutch Safety Board, which led the air-safety probe, last October said a Russian-made Buk missile system struck the Boeing aircraft, causing it to break apart and plunge to the ground. The launch location was within a 320-square-kilometer (124-square-mile) area in eastern Ukraine, the safety board said, without identifying who fired the missile.

Relatives of the victims have expressed anger at the slow pace of the criminal investigation and that, more than two years after the crash, the perpetrators still haven't been identified and brought to justice.

Russian Defense Ministry spokesman Major Gen. Igor Konashenkov this week accused Ukraine of withholding information on the incident.
