The United Nations marked the 11th anniversary of the downing of Malaysia Airlines Flight MH17 on 17 July, with Secretary-General Antonio Guterres expressing solidarity with the families of the 298 victims and urging all governments to cooperate fully with ongoing efforts to hold those responsible to account, in line with Security Council Resolution 2166. Commemorations were held at the National Monument MH17 in Vijfhuizen and in capitals around the world, where officials from Ukraine, the Netherlands and other affected nations renewed demands for justice. The observances come a week after the European Court of Human Rights ruled on 10 July that Russia bears responsibility for the 2014 missile strike, bolstering previous findings by the Dutch-led Joint Investigation Team. Flight MH17, a Boeing 777 traveling from Amsterdam to Kuala Lumpur, was shot down on 17 July 2014 over eastern Ukraine by a Russian-made Buk surface-to-air missile, killing 283 passengers—mostly Dutch nationals—and 15 crew members. Moscow has continued to deny involvement, but international investigators and courts have concluded that the missile system belonged to Russian forces or their proxies. Families and officials say securing accountability remains essential to preventing similar tragedies.
