New York is lighting the spire of the World Trade Center in the colors of the French flag to honor the people of The City of Lights, as Paris is known, who were killed in deadly attacks across the French capital Friday.
New York Governor Andrew Cuomo said Friday "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."
The World Trade Center, the tallest building in the U.S., is built on the site of the September 11, 2001 attacks on New York.
The Parisian attacks are among the deadliest in the West since 2001 terrorist attacks on the U.S., and come just 10 months after another deadly attack in Paris on the satirical magazine Charlie Hebdo.
U.S. President Barack Obama spoke late Friday by telephone with French President Francois Hollande, reassuring the French leader that the U.S. is a staunch supporter of France and is ready to provide any support needed in the investigation of the latest terrorist attack on the French capital.
American cities boosted their security measures following the Paris attacks. Both New York and Washington deployed additional security forces "out of an abundance of caution."
