Americans to mark 25 years since September 11 attacks amid enduring grief, reflection

Americans will commemorate the 25th anniversary of the September 11 attacks, which killed nearly 3,000 people and had a lasting impact on US foreign policy, domestic politics, and public attitudes toward security.

The anniversary is a tribute to the lives lost and the heartbreak that followed, with memorials in the US and Ireland honoring the victims and heroes, including at least 18 Irish citizens and countless Irish Americans.
