September 11 attacks
The September 11 attacks (also referred to as 9/11) were a series of four coordinated terrorist attacks by the Islamic terrorist group al-Qaeda against the United States on the morning of Tuesday, September 11, 2001. The attacks killed 2,996 people, injured over 6,000 others, and caused at least $10 billion in infrastructure and property damage. Additional people died of 9/11-related cancer and respiratory diseases in the months and years following the attacks.
Terrorism Risk Insurance Act
Before the September 11 attacks, business insurers generally neither charged for nor specifically excluded terrorism coverage. The scope of the 9/11 attacks and the resulting $40 billion estimated insured loss changed perceptions dramatically. It was the worst terrorist attack on record for both property and fatalities and the worst international attack on American soil since the Japanese surprise attack on Pearl Harbor, as nearly 3,000 people lost their lives in New York City, Washington, D.C., and Stonycreek Township near Shanksville, Pennsylvania.
