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.
Ahmed Omar Saeed Sheikh
"The Wall Street Journal" was one of the only Western news organisations to follow up on the story, citing the "Times of India": "US authorities sought General Mahmud Ahmed's removal after confirming that $100,000 was wired to WTC hijacker Mohamed Atta from Pakistan by Ahmad Umar Sheikh at the insistence of General Mahmud." Another Indian newspaper, the "Daily Excelsior", quoting FBI sources, reported that the "FBI's examination of the hard disk of the cellphone company Saeed had subscribed to led to the discovery of the "link" between him and the deposed chief of the Pakistani ISI, Mahmud Ahmed. And as the FBI investigators delved deep, reports surfaced with regard to the transfer of $100,000 to Mohamed Atta, one of the ringleaders of the September 11 attacks, who flew a hijacked Boeing commercial airliner into the World Trade Center. General Mahmud Ahmed, the FBI investigators found, fully knew about the transfer of money to Atta."
