The Duke of Cambridge has paid tribute to the Belgian people for their "courageous resistance" in the First World War, as he gave a speech in Liege marking the 100th anniversary of the start of the war.
He said: "Among the very first victims [of WW1] were the people of Belgium whose resistance was as gallant as their suffering was great.
"The magnificent war memorial where we gather today honours the city of Liege and its people for their courageous resistance in 1914.
"The memorial and this ceremony also honours all Belgians who fought, suffered and died in the Great War".
As the Lights Out event to remember those who fought and died in WWI happened last night ITV asked our viewers what they did to take part.
Lights on some of Britain's most famous landmarks were extinguished between 10pm and 11pm to remember those who died in WWI.
