A U.S. flag was unfurled on the side of the Pentagon on Wednesday (September 11) to mark twenty-five years after the deadliest attack on U.S. soil, and commemorate the nearly 3,000 people killed when hijacked planes slammed into the World Trade Center, the Pentagon and a field in Pennsylvania.

U.S Secretary of Defence Peter Hegseth joined military personal during the ceremony where the national anthem was sung to mark the anniversary as the U.S flag was unfurled.

The attacks shaped generations of Americans who lived through the day or grew up in its aftermath, influencing U.S. foreign policy, domestic politics and public attitudes toward security.
