<P0-S0> The Federal Detention Center (FDC Philadelphia) is a United States Federal prison in Center City, Philadelphia, Pennsylvania which holds male and female inmates prior to or during court proceedings, as well as inmates serving brief sentences. <P0-S1> It is operated by the Federal Bureau of Prisons, a division of the United States Department of Justice. <SEP> <P1-S0> George Pocheptsov, who is sometimes also referred to as "Georgie", was born in Philadelphia, Pennsylvania, in 1992 to Ukrainian parents. <P1-S1> When Pocheptsov was eleven months old, his father was diagnosed with brain cancer; and he died in 1995, at the age of forty. <P1-S2> Though he was a toddler, his mother gave him a pencil and some paper to keep him busy. <P1-S3> At seventeen months old, he drew a replica of an antique car parked across the street. <P1-S4> At a young age, Pocheptsov was drawing jesters, pregnant women, and four-headed giraffes, all in bright color schemes. <P1-S5> He started to paint six months before he started to talk. <SEP> <P2-S0> Journalist Yosri Fouda of the Arabic television channel Al Jazeera reported that in April 2002 Khalid Sheikh Mohammed admitted his involvement in the attacks, along with Ramzi bin al-Shibh. <P2-S1> The 9/11 Commission Report determined that the animosity towards the United States felt by Mohammed, the principal architect of the 9/11 attacks, stemmed from his "violent disagreement with U.S. foreign policy favoring Israel". <P2-S2> Mohammed was also an adviser and financier of the 1993 World Trade Center bombing and the uncle of Ramzi Yousef, the lead bomber in that attack.Mohammed was arrested on March 1, 2003, in Rawalpindi, Pakistan, by Pakistani security officials working with the CIA. <P2-S3> He was then held at multiple CIA secret prisons and Guantanamo Bay where he was interrogated and tortured with methods including waterboarding. <P2-S4> During U.S. hearings at Guantanamo Bay in March 2007, Mohammed again confessed his responsibility for the attacks, stating he "was responsible for the 9/11 operation from A to Z" and that his statement was not made under duress. <SEP> <P3-S0> the oklahoma city bombing was a domestic terrorist truck bombing on the alfred p. murrah federal building in downtown oklahoma city, oklahoma, united states on april 19, 1995. perpetrated by timothy mcveigh and terry nichols, the bombing happened at 9: 02am and killed at least 168 people, injured more than 680 others, and destroyed one - third of the building. <P3-S1> the blast destroyed or damaged 324 other buildings within a 16 - block radius, shattered glass in 258 nearby buildings, and destroyed or burned 86 cars, causing an estimated $652 million worth of damage. <P3-S2> extensive rescue efforts were undertaken by local, state, federal, and worldwide agencies in the wake of the bombing, and substantial donations were received from across the country. <P3-S3> the federal emergency management agency (fema) activated 11 of its urban search and rescue task forces, consisting of 665 rescue workers who assisted in rescue and recovery operations. <P3-S4> until the september 11 attacks in 2001, the oklahoma city bombing was the deadliest terrorist attack in the history of the united states, and remains the deadliest incident of domestic terrorism in the country's history. <SEP> <P4-S0> On 16 September 2001, at Camp David, President George W. Bush used the phrase war on terrorism in an unscripted and controversial comment when he said, "This crusade – this war on terrorism – is going to take a while, ... " Bush later apologized for this remark due to the negative connotations the term crusade has to people, e.g. <P4-S1> of Muslim faith. <P4-S2> The word crusade was not used again. <P4-S3> On 20 September 2001, during a televised address to a joint session of congress, Bush stated that, "(o)ur 'war on terror' begins with al-Qaeda, but it does not end there. <P4-S4> It will not end until every terrorist group of global reach has been found, stopped, and defeated." <SEP> <P5-S0> the obama administration began to reengage in iraq with a series of airstrikes aimed at isis beginning on 10 august 2014. on 9 september 2014 president obama said that he had the authority he needed to take action to destroy the militant group known as the islamic state of iraq and the levant, citing the 2001 authorization for use of military force against terrorists, and thus did not require additional approval from congress. <P5-S1> the following day on 10 september 2014 president barack obama made a televised speech about isil, which he stated "our objective is clear: we will degrade, and ultimately destroy, isil through a comprehensive and sustained counter-terrorism strategy". <P5-S2> obama has authorized the deployment of additional u.s. forces into iraq, as well as authorizing direct military operations against isil within syria. <P5-S3> on the night of 21/22 september the united states, saudi arabia, bahrain, the uae, jordan and qatar started air attacks against isis in syria. <P5-S4> [citation needed]
