United States commemorates 25 years since September 11 terrorist attacks

Americans observed the 25th anniversary of the September 11 attacks on Tuesday, honouring the nearly 3,000 people killed in coordinated strikes on the World Trade Center in New York, the Pentagon in Washington, and a crashed aircraft in Pennsylvania. The attacks, carried out by the extremist group al-Qaeda, represented one of the deadliest incidents on American soil and triggered sweeping changes to domestic security policies and international relations.

Memorial services took place across the nation, with ceremonies at ground zero in Manhattan drawing survivors, families of victims, and government officials. President Joe Biden issued a proclamation acknowledging the resilience displayed by emergency responders and citizens in the aftermath of the tragedy, while emphasizing national unity and shared sacrifice.

The anniversary serves as a reminder of the geopolitical consequences that unfolded over the subsequent two decades, including military operations in Afghanistan and Iraq, enhanced airport security measures, and expanded surveillance frameworks. Security analysts note that while subsequent major terrorist attacks on American soil have been prevented, the legacy of 9/11 continues to influence defence and foreign policy decisions.

Veterans' organisations and community groups across the nation organised vigils and educational events to ensure younger generations understand the historical significance of the attacks and their enduring impact on American society and global counterterrorism efforts.
