United States invasion of Afghanistan
On the morning of 11 September 2001, al-Qaeda carried out four coordinated attacks on the United States. Four commercial passenger jet airliners were hijacked. The hijackers – members of al-Qaeda's Hamburg cell – intentionally crashed two of the airliners into the Twin Towers of the World Trade Center in New York City. Both buildings collapsed within two hours from fire damage related to the crashes, destroying nearby buildings and damaging others. The hijackers crashed a third airliner into the Pentagon in Arlington County, Virginia. The fourth plane crashed into a field near Shanksville, Pennsylvania, after some of its passengers and flight crew attempted to retake control of the plane, which the hijackers had redirected toward Washington, D.C., to target the White House or the United States Capitol. No flights had survivors. In total, 2,996 people, including the 19 hijackers, died and more than 6,000 others injured in the attacks. According to the New York State Health Department, 836 first responders, including firefighters and police personnel, had died as of June 2009.
Richard Williamson (bishop)
Williamson supports conspiracy theories regarding the assassination of John F. Kennedy, and the World Trade Center controlled demolition conspiracy theory, denying that the September 11 attacks were foreign terrorist attacks and claiming they were instead staged by the U.S. government. He has also said that the 7 July 2005 London bombings were an "inside job" and propagated rumours about the likelihood of a nuclear attack on the London Olympics in 2012.
