Harrowing images of the carnage of the World Trade Centre
Today marks 18 years of the horrific terrorist attacks that happened in the United States of America. 9/11 attacks were a series of four coordinated suicide attacks that took place on September 11, 2001.
The attacks killed nearly 3,000 people and injured over 6,000 others. The 9/11 attacks were the deadliest on the US soil since the Pearl Harbour bombing in 1941 that launched the US into World War II.
