A witness and media reports say a small aircraft has crashed into Beijing’s tallest building, the CITIC Tower, triggering evacuations and drawing a large police and ambulance presence. Photos show what appeared to be a hole in the glass facade on one side of the tower. Images on social media appeared to show debris from a small aircraft near the skyscraper, but their authenticity couldn't be confirmed. The cause of the crash remains unclear, and authorities have not issued a statement. The 108-story tower is one of Beijing's most recognizable landmarks. Recently, Beijing authorities enacted new curbs on its tightly regulated airspace.
