The terrorist organization Islamic State has changed in recent months, Pentagon spokesman John Kirby said.
"We know that oil revenue is no longer the lead source of the Islamic State's income in dollars," Gazeta.ru cited him as saying.
Due to the success of the international coalition, IS is largely in a defensive posture now, they "are losing gound". "This is a different group than it was seven months ago. I’m not saying they are not still dangerous. I'm not saying they are not still barbaric, but they are different," Kirby reckons.
At the same time, he assured that the United States is going to continue to fight Islamic State together with its allies.
