Families of those killed when a Buk missile blew Malaysia Airlines Flight 17 out of the sky above Ukraine in 2014 are calling on US President Donald Trump to press his Russian counterpart Vladimir Putin to provide answers about the downing.
In a letter to Trump published Friday on Twitter, relatives of about 30 of the 298 passengers and crew killed on July 17, 2014, say "we have a right to know what happened to our loved ones."
