New York Governor Andrew Cuomo said the 408-ft. spire atop One World Trade Center will be lit up in the colors of the French flag Friday night and “in the days ahead” in memory of the at least 100 people feared dead following multiple terror attacks across the French capital that led President François Hollande to shut down the country’s borders and declare a state of emergency.

“Today, and in the days ahead, New York will light One World Trade Center in blue, white and red as we stand in solemn solidarity with the people of France, just as they have done for us in our own times of tragedy,” Cuomo said in a statement.

Other monuments also paid tribute to France.

San Francisco City Hall tweeted a photo of the French flag flying from the building and changed its avatar to a photo of the building lit up in the flag’s colors.

Canadian news outlets have been tweeting photos of Toronto’s CN Tower in blue, white, and red, while The Dallas Morning News and other local media outlets have been tweeting photos of the city’s Omni Hotel in blue, white, and red.
