Pope Francis said it was unfair to identify Islam with violence and terrorism, NBC News reported.
"I don't like to talk about Islamic violence. Not all Muslims are violent. In every religion there are small groups of fundamentalists," the pope said on his flight back to Rome from Poland, where he presided over World Youth Day.
The pope suggested that capitalism is another form of terrorism.
"When you place at the center of the world economy the 'God of Money,' that's terrorism against all humanity."
