A 2007 Pew Research Center study of several nations throughout the Muslim world showed that opposition to suicide bombing in the Muslim world is increasing, with a majority of Muslims surveyed in 10 out of the 16 of the countries responding that suicide bombings and other violence against civilians is "never" justified, though an average of 38% believe it is justified at least rarely. Opposition to Hamas was the majority opinion in only 4 out of the 16 countries surveyed, as was opposition to Hezbollah. The Pew Research Study did not include Iran, Iraq, Saudi Arabia, Syria, Afghanistan, Tunisia, Libya, and Algeria in the survey, although densely populated Muslim countries such as Pakistan, Egypt, Indonesia, and Bangladesh were included.
A YouGov survey for the Daily Telegraph, published two weeks after the July 2005 bombings in the London Underground, showed that 88% of British Muslims were opposed to the bombings,
while 6% (about 100,000 individuals) fully supported them, and one British Muslim in four expressed some sympathy with the motives of the bombers. A 2007 poll found that one Muslim in four thought the Government had staged the bombings and framed the Muslims convicted. A 2011 study by Pew Research showed that 64% of Muslim Americans thought that there was not much or no support among them for extremism, while 6% thought there was a great deal, and 15% thought there was a fair amount.
