(Reuters) - Police and intelligence services have disrupted 11 plots against New York City since the September 11, 2001, attacks destroyed the World Trade Center in Manhattan, according to the New York Police Department.
Here is a list of those plots:
* 2003 - Five Bahraini men were arrested on the border between Bahrain and Saudi Arabia. An investigation uncovered a plan on a computer to detonate an explosive device on the New York City subway system that would emit poisonous gas. The device was called the “mubtakkar.”
* 2003 - Iyman Faris, a truck driver from Columbus, Ohio, was arrested after communicating with al Qaeda’s Khalid Sheikh Mohammed and plotting to destroy the Brooklyn Bridge. Faris was convicted of conspiring to provide material support to al Qaeda and is serving a 20-year prison term.
* 2004 - A group of men led by Dhiren Barot, a senior al Qaeda operative, was arrested in Britain for planning to attack targets in Britain and the United States. Barot admitted to a plot to blow up the New York Stock Exchange and carry out attacks in Britain with gas-filled limousines and a “dirty bomb,” and was jailed in November 2006 for a minimum of 30 years. Seven other Britons linked to the plot were jailed for a total of 136 years in June 2007.
* 2004 - A Pakistani immigrant, Shahawar Matin Siraj, was arrested for planning to bomb New York City’s Herald Square subway station, and was sentenced in 2007 to 30 years in prison.
* 2006 - Lebanese man Assem Hammoud was arrested in Beirut, accused of plotting suicide bomb attacks on trains running through tunnels under the Hudson River between New York City and New Jersey.
* 2006 - British police uncovered an al-Qaeda plot to blow up transatlantic airliners bound for North America using bombs made from liquid explosives.
* 2007 - Four men were accused of planning to blow up jet fuel tanks at New York’s John F. Kennedy International Airport and part of the 40-mile (64-km) pipeline feeding them from New Jersey. Russell de Freitas, a U.S. citizen born in Guyana, and Abdul Kadir of Guyana were convicted of the plot and face sentencing in December. Guyanese Abdel Nur pleaded guilty and awaits sentencing, while Kareem Ibrahim of Trinidad and Tobago was too ill to stand trial but may be tried later.
* 2008 - U.S. authorities warned of a possible al Qaeda threat to transit systems in and around New York City over the Thanksgiving holidays, one of the busiest U.S. travel periods of the year. Authorities said al Qaeda may have discussed such attacks in September 2008.
* 2009 - Four men were arrested and charged over a plot to blow up two New York synagogues and shoot down military planes with stinger missiles. The men -- James Cromitie, David Williams, Onta Williams and Haitian citizen Laguerre Payen -- are currently on trial in Manhattan federal court.
* 2009 - Afghan immigrant Najibullah Zazi was arrested and charged with plotting a suicide bombing campaign on Manhattan’s subway system. U.S. authorities disrupted the plot before Zazi and his accused accomplices were able to carry it out. Zazi and another Afghan-born man pleaded guilty in 2010.
* 2010 - Pakistani-born U.S. citizen Faisal Shahzad pleaded guilty to attempting to set off a car bomb in New York’s Times Square. He was sentenced to life in prison without parole.
