US to mark anniversary of 9/11 terrorist attacks

Americans will commemorate the Sept 11 attacks on that day in 2019 with solemn memorials in major cities, and a presidential tribute to the victims 18 years after the deadliest terrorist attack on US soil.

In New York City, a traditional commemoration ceremony will be held at the site where the World Trade Center's twin towers collapsed, with a moment of silence observed at 8:46 am, the exact time the first hijacked airplane struck the North Tower.

The United States came under multiple terrorist attacks on Sept 11, 2001, after four civilian aircraft were hijacked and steered toward prominent US buildings.

Three of the planes hit their targets in New York and Washington, DC, while the fourth crashed en route to Washington as its passengers battled for control of the aircraft with the hijackers. The attacks left nearly 3,000 killed or missing.
