The United States celebrates today the 25th anniversary of the September 11, 2001 attacks, the deadliest terrorist attack in history on American soil. The attack caused nearly three thousand deaths, among which nine Portuguese and Lusodescent victims.
The commemorative ceremonies are taking place at the four sites hit by the attacks. In New York, the ceremonies are held at "Ground Zero," where the Twin Towers of the World Trade Center once stood. The Pentagon, headquarters of the Department of Defense, in the outskirts of Washington, and Shanksville, Pennsylvania, are the other two sites of tribute.
The attacks were carried out by terrorists of the Al-Qaeda network, who hijacked four commercial passenger planes. Two of the planes crashed into the Twin Towers, one hit the Pentagon, and the fourth crashed in a field in Shanksville, after a struggle between the passengers and the hijackers.
