Today Tuesday, 1th September 2018 marks the 17th anniversary of the terrorist attack on the World Trade Center which devastated America and shocked the world.
According to reports as at the time of filing, about four planes where hijacked in 9/11
Two planes were flown into the Twin Towers in New York whilst a third crashed into the Pentagon in Arlington County, Virginia.
A fourth plane was hijacked but the passengers fought the terrorists and managed to make sure the plane did not reach its intended target (thought to be the Capitol or the White House).
That fourth plane crashed near Shanksville, Pennsylvania and no one on board survived.
About 343 firefighters were killed in the attacks, as were 72 law enforcement officers and 55 people in the military.
9/11 remains the worst terrorist attack in history, in terms of death toll, and the most lethal foreign attack on America since the bombing of Pearl Harbor during World War II in 1941.
