On each anniversary of the September 11, 2001, terrorist attacks on the United States, Americans gather at memorials and events across the country. They pause to remember the nearly 3,000 people who died in New York, Virginia and Pennsylvania on that day. Besides the three memorials built at the sites where each attack took place, other U.S. cities and towns have created their own annual 9/11 events and constructed local memorials as reminders of the lives lost.

Here are some scenes from tributes in 2018:
