World Trade Center Health Program
On September 11, 2001, 19 terrorists associated with the Islamist militant group al-Qaeda hijacked four passenger jets in a series of suicide attacks on the United States, killing 2,996 people and injuring more than 6,000 others. Hijackers flew planes into two main towers of the World Trade Center, resulting in the collapse of three buildings of the World Trade Center complex, and the Pentagon, resulting in the partial destruction of the western side in the building. The resulting dust cloud due to the collapse of the World Trade Center covered Manhattan for days and contained thousands of tons of toxic debris, including asbestos and other known carcinogens. Another hijacked plane crashed into a field in Shanksville, Pennsylvania following an attempt by the passengers to retake control of the plane. No one in the airliners survived.
As of 2011, approximately 18,000 people have received medical treatment for illnesses related to toxic dust from the World Trade Center site. A study of rescue workers released in April 2010 found that all those studied had impaired lung functions, and that 30–40% were reporting little or no improvement in persistent symptoms that started within the first year of the attack. In 2011 a major research study showed significant long term medical and psychological effects among first responders to the World Trade Center site. These effects include elevated levels of asthma, sinusitis, Gastroesophageal reflux disease and posttraumatic stress disorder.
Bowling Green massacre
On January 29–30, 2017, White House Press Secretary Sean Spicer stated that Islamist terrorists perpetrated a terrorist attack in Atlanta, even though Atlanta has never had a terrorist attack carried out by Islamists. The initial comment was made on ABC's "This Week", and then Spicer repeated the claim on MSNBC's "Morning Joe" the following day. Spicer later said that he meant Orlando, referring to the 2016 Orlando nightclub shooting, which was carried out by U.S.–born Omar Mateen. There have been two terrorist attacks in Atlanta: the 1996 Centennial Olympic Park bombing, which was carried by domestic terrorist Eric Rudolph, and the 1958 Hebrew Benevolent Congregation Temple bombing.
