( CNN ) -- First came the devastating news that Malaysia Airlines Flight 17 had crashed . Then , the horrifying accusation that someone shot it out of the sky . And now this -- the fear that their loved ones ' remains might never make it home . `` We want to know where my brother ... is right now , and we still do n't , '' Paul de Kuijer told CNN on Monday . Authorities have said a train carrying the bodies of hundreds of victims is on its way to Kharkiv , Ukraine . But de Kuijer said he has n't gotten any word about whether his brother Pim is on it . `` We do n't know whether they recovered his body , whether it 's on the train , whether it will be coming to the Netherlands soon , '' he said . `` These are the big questions that we have right now . '' The 298 people aboard Malaysia Airlines 17 when it crashed on Thursday left behind hundreds of family members across the globe . Some say their voices are getting lost in an international political scuffle as world leaders face off over what happened to the downed jet . `` The passengers aboard Malaysia Airlines Flight 17 had nothing to do with the conflict in eastern Ukraine . They were families heading on vacation , students returning home from abroad , researchers trying to eradicate a deadly disease , '' U.S . Ambassador to the United Nations Samantha Power said Monday . `` Those who were killed deserve to be treated with dignity and their families are crying out , as we have heard , for closure . '' As presidents , prime ministers and ambassadors pointed fingers over who was responsible for the crash , father Hans de Borst spoke out in a Facebook post . He accused Russian President Vladimir Putin , the Ukrainian government and separatists of murdering his 17-year-old daughter , who was nearing the end of high school and planning to study engineering . `` She was looking forward to it ! '' de Borst wrote . `` But suddenly she is not here anymore ! She has been shot out of the sky , in an unknown country , where there is a war going on ! Aforementioned misters , I hope you 're proud to have shot her . ... And that you will be able to look at yourself in the mirror tomorrow morning . '' Dutch Foreign Minister Frans Timmermans said bringing the remains of the 193 Dutch citizens who died in the crash home was his country 's top priority . He decried what he called disturbing reports of how bodies had been treated at the scene of the crash . `` Just imagine that you first get the news that your husband was killed . and then within two or three days , you see images of some thug removing a wedding band from their hands . Just imagine that this could be your spouse , '' he said . `` To my dying day , I will not understand that it took so much time for the rescue workers to be allowed to do their difficult jobs , and that human remains should be used in a political game . '' Even as reports that thieves have been picking over bodies at the scene draw sharp condemnation from international officials , Silene Fredriksz said she was n't worried about material things . Until the remains of her son and his girlfriend are returned , Fredriksz said she 's paralyzed . `` I can do nothing but wait for the bodies , '' she told CNN . `` They can have everything , but the bodies have to come back . Take their iPhones , take their money , take everything . '' In Malaysia , a group of families of victims meeting with government officials had just one request , state media reported . `` That the bodies be brought back in whatever condition , '' Malaysian government minister Datuk Seri Rohani said . In Britain , Hugo Hoare told The Mirror that he was worried about whether rebels were taking care of the bodies of his 59-year-old brother Andrew and the other crash victims . `` I just hope whatever they are doing is humane and their intention is just to release them at the appropriate time . The first thing I thought was , what if they are going to use them as a bargaining chip ? '' Hoare said . `` We just have to follow normal pressure through diplomatic channels and just hope there is a decent resolution at the end of it . '' Standing at Amsterdam 's Schipohl Airport , just meters away from the place where her son and his girlfriend checked in for their flight last week , Fredriksz asked Russian President Vladimir Putin for help . `` Mr. Putin , '' she said , `` please take care of my son and my daughter , to bring them home . '' Her son , Bryce , 23 , and his girlfriend Daisy Oehlers were on their way to Bali when the plane was downed in war-torn eastern Ukraine . Fredriksz had bought the `` beautiful young couple '' their tickets for a holiday after the death of Oehlers ' mother 2Â½ months ago . `` I paid their tickets to give them four weeks holiday to find their happiness again , '' she said . Supported by family members , Fredriksz , sometimes in tears , described searching through grisly photos on social media in an effort to find her son . `` I saw pictures on Facebook of bodies . Complete bodies . I had to look at it because maybe my son was on the picture , '' she said . Fredriksz could n't find him . But that has n't dampened her resolve . She knows she wants to bring Bryce and Daisy together again . `` Here . They have to be buried together , '' she said from Amsterdam . `` They died together . They loved each other . They have to be together forever . '' CNN 's Susannah Cullinane and Jim Sciutto contributed to this report .
