Dutch Prime Minister Mark Rutte joined mourners for the memorial ceremony of the downing of flight MH17 at the MH17 National Memorial in Vijfhuizen on Tuesday. Footage shows the Prime Minister as he arrives and greets others at the ceremony, as well as flags at half-mast to honour those who died in the crash. Piet Ploeg, Board member of the MH17 Memorial Foundation, explained that it may take... Еще a long time to find conclusive evidence of who was behind the disaster, saying «This is complex subject. It's an investigation of a crime that was committed in Ukraine. It's unbelievably complex geopolitically. I can tell you that there are around 150,000 taped phone conversations that need to be analysed, and also a few billion website pages.» «We would rather have that its done right versus it being rushed. Quality precedes time,» Ploeg added . Malaysia Airlines flight MH17 was en route to Kuala Lumpur from Amsterdam when it was downed in the skies over eastern Ukraine on July 17, 2014. All 298 people on board were killed.
