On Tuesday morning, two explosions occurred at Zaventem Airport and another ripped through the Maelbeek metro station in Brussels, killing 28 people and injuring dozens more.
In a demonstration of solidarity, the city of Paris has changed its Twitter avatar to the colors of the Belgian flag. Now, when you visit the Paris Twitter account, it looks like this.
According to Twitter, the Eiffel Tower will also be lit up in the Belgian colors Tuesday night as a show of support.
Ce soir, @LaTourEiffel sera illuminée aux couleurs de la Belgique.
Paris est solidaire de #Bruxelles. #NousSommesUnis
