Prosecutors involved in the international investigation into the downing last year of Malaysia Airlines Flight 17 say they do not yet have specific suspects for possible prosecution.

Fred Westerbeke, the Dutch prosecutor leading the investigation, said Tuesday the international team has a number of “persons of interest” but declined to identify them.

The flight heading from Amsterdam to Kuala Lumpur was brought down July 17 over eastern Ukraine, killing all 298 people on board.

The five-nation team involved in the criminal investigation has said that the most likely scenario for the cause was that a surface-to-air missile shot it down.

Both pro-Russian rebels and Ukrainian forces have denied involvement.

Westerbeke says the probe will likely take until at least the end of this year.
