Americans believe that the Islamic State group, or ISIS, poses the most serious threat to the United States in the next decade, according to a poll.
Eighty four per cent of those quizzed by Gallup for the poll said they believed ISIS, the extremist Sunni organization which has seized stretches of Iraq and Syria, committing scores of atrocities, poses a "direct threat to the USA."
