Obama is speaking at the close of a nuclear security summit in Washington. He says the Islamic State is losing territory and its oil infrastructure and says morale among its fighters is declining.
Obama says the group is a threat to all nations. He’s noting that almost all the nations participating in the summit have had citizens join IS in Iraq and Syria.
The president says IS has become the world’s most active extremist group.
He says the U.S. is already seeing IS spread beyond Iraq and Syria, pointing to recent attacks in Belgium and Turkey.
