Question: What is the biggest terrorist attack by the Islamic group on whom Bush said the 'war on terror' begins, against the country where the Sunday Mercury can be found?

The Sunday Mercury (1839–1896) (sometimes referred to as the New York Sunday Mercury) was a weekly Sunday newspaper published in New York City that grew to become the highest-circulation weekly newspaper (at least by its own claims) in the United States at its peak. It was known for publishing and popularizing the work of many notable 19th-century writers, including Charles Farrar Browne and Robert Henry Newell, and was the first Eastern paper to publish Mark Twain. It was also the first newspaper to provide regular coverage of baseball, and was popular for the extensive war correspondence from soldiers it published during the Civil War. <SEP> 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. of Muslim faith. The word crusade was not used again. It will not end until every terrorist group of global reach has been found, stopped, and defeated." 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. <SEP> 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. 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. 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". He was then held at multiple CIA secret prisons and Guantanamo Bay where he was interrogated and tortured with methods including waterboarding. 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> on 7 january 2015, two french muslim extremists attacked the paris headquarters of charlie hebdo and killed thirteen people, and on 9 january, a third terrorist killed four hostages during an attack at a jewish grocery store at porte de vincennes. on 11 january an estimated 1.5 million people marched in paris–along with international political leaders–to show solidarity against terrorism and in defence of freedom of speech. ten months later, 13 november 2015, came a series of coordinated terrorist attacks in paris and saint-denis claimed by the 'islamic state' organisation isil ('daesh', isis); 130 people were killed by gunfire and bombs, and more than 350 were injured. seven of the attackers killed themselves and others by setting off their explosive vests. on the morning of 18 november three suspected terrorists, including alleged planner of the attacks abdelhamid abaaoud, were killed in a shootout with police in the paris suburb of saint-denis. president hollande declared france to be in a three-month state of emergency. <SEP> 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. 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". obama has authorized the deployment of additional u.s. forces into iraq, as well as authorizing direct military operations against isil within syria. 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.
