A small aircraft crashed into Beijing’s tallest building, the 109-story CITIC Tower, on Friday. The incident occurred in one of the city’s busiest commercial districts, causing debris and aircraft parts to fall onto the streets below. People inside the building and on the streets were seen fleeing in panic as wreckage rained down.

Footage shared on social media showed debris falling from the skyscraper, including what appeared to be part of the plane’s tail. The New York Times verified a video of the event, confirming the fall of debris and the rush of people seeking safety. The building, located in the heart of Beijing, is among the most secure sites in the city.

Authorities have not yet confirmed whether there were any casualties or injuries resulting from the crash.
