Ukraine has promised to cooperate in a so-called 'fact-finding investigation' that revolves around the question why the airspace was not closed at the time of the shooting of MH17. The Ministry of Foreign Affairs confirmed this to on Thursday.

Foreign Minister Stef Blok is currently visiting Kiev. After talking with President Volodymyr Zelensky, he announced during a press conference that the country is cooperating.

On Thursday afternoon, Blok also announced via Twitter that "The Netherlands and Ukraine continue to work closely together" when it comes to MH17.

A large majority of the House of Representatives asked for such an investigation earlier this month. The Dutch Safety Board (OvV) has previously a; concluded that there were enough indications for the country in the days before the downing of MH17 to close the airspace.

The plane departed from Amsterdam five years ago. The flight was brought down above Ukraine by a stoop-missile. The 298 passengers all died, of whom 196 were Dutch.

The Joint Investigation Team (JIT) announced in July this year that they would prosecute three Russians and one Ukrainian for their role in bringing down flight MH17.

The trial against Igor Girkin, Sergey Dubinsky, Oleg Pulatov and Leonid Kharchenko will start in March of next year.
