The Eiffel Tower was illuminated with colors of black, red and yellow to pay tribute to the victims of the Brussels attacks, which killed dozens on Tuesday.
Anne Hidalgo, the mayor of Paris, tweeted earlier in the day: "In solidarity with the people of Brussels, Paris will light up the Eiffel Tower in the colors of the Belgian flag tonight."
New York Gov. Andrew Cuomo also announced One World Trade Center will light up in Belgian colors Tuesday night.
In a statement, Cumo said: "New York stands shoulder to shoulder with the people of Belgium and the rest of the world in rejecting the hate and extremism behind this violence. As we have seen time and again, when we are united, terror has never prevailed and never will."
Other landmarks around the world are also expressing solidarity with the victims of the Brussels attacks by displaying the colors of the Belgian flag, including:
The Brandenburg Gate in Berlin:
The Trevi fountain in Rome:
The courthouse in Lyon, France:
Burj Khalifa, the world-renowned skyscraper in Dubai:
