The Eiffel Tower lit up in the colors of the Belgian flag Tuesday night in a show of solidarity following the early morning terrorist attacks in Brussels that killed at least 34 people and injured nearly 200 others.
The tower was lit in the black, yellow and red of the Belgian flag at the request of Paris' Mayor Anne Hidalgo, according to a statement on the monument’s official website Tuesday.
Hidalgo tweeted her support for the people of Belgium. She wrote: "As an act of solidarity with the residents of Brussels, #Paris will illuminate the Eiffel Tower tonight with the colors of the Belgian flag. #WeAreUnited."
French President Francois Hollande also spoke out. "I've expressed my solidarity with the Belgian people. Terrorists struck Brussels but it was Europe that was targeted," he wrote on Twitter.
The tower will be lit from nightfall until 1 a.m. local time. It is typically illuminated each night and sparkles its lights for five minutes on the hour, but on Tuesday night, in a sign of mourning, it won't sparkle.

The monument often takes on colors significant to celebrations and holidays, like glowing with red lights for Chinese New Year in 2004 or twinkling green lights for the Rugby World Cup in 2007.
But in the immediate aftermath of the deadly Paris terror attacks in November that left 129 dead, the tower went dark for a night. Days later, it was illuminated again with the red, white and blue colors of the French flag and a projection of Paris' city motto, "Fluctuat Nec Mergitur": tossed by the waves but does not sink.
