US President Barack Obama has called Isis "a bunch of killers with good social media".
He made the comments at a press conference in Malaysia at the end of a nine-day trip abroad.
Speaking of the terror group responsible for the recent attacks in Paris, Obama said "they are dangerous" and have caused great hardship to "an overwhelming majority of people".
CNN reports he maintained the global coalition formed to destroy Isis "will not relent".
"We will not accept the idea that terrorist assaults on restaurants and theatres and hotels are the new normal, or that we are powerless to stop them.
