The United States commemorates this Friday the 25th anniversary of the September 11, 2001 attacks, which caused 2,977 deaths at the World Trade Center, the Pentagon and in Shanksville. The main ceremony takes place at Ground Zero in New York, bringing together victims' families, survivors, emergency teams and much of the American political class.
Donald Trump does not participate in the main Ground Zero ceremony, instead attending the event held at the Pentagon in Arlington. This absence contrasts with the presence of four former U.S. presidents at the main commemoration ceremony.
The article does not provide additional details about which former presidents were present or about the specific activities that took place during the commemoration ceremonies.
