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.
Foreign policy of the Bill Clinton administration
On February 26, 1993, thirty-six days after Clinton took office, terrorists who the CIA would later reveal were working under the direction of Osama bin Laden detonated a timed car bomb in the parking garage below Tower One of the World Trade Center in New York City (see the World Trade Center bombing). Clinton responded by ordering his National Security Council, under the direction of Anthony Lake, and the FBI to find and punish those responsible. The FBI was able to quickly identify the vehicle used in the bomb from a remnant found in the rubble: a Ryder rental van, which had been reported stolen in Jersey City, New Jersey the day before. The truck was rented by Mohammed Salameh, whom the FBI immediately detained. Similar evidence led to the arrests of other plotters behind the attack, including Nidal Ayyad, Mahmoud Abouhalima, Ahmad Ajaj, and Ramzi Yousef—who was identified as the key player in the bombing. All men were tried and convicted for the bombing and other terrorists activities.
