US President Barack Obama has said the United States and its allies will not relent in its fight to combat Islamic State extremists and would hunt down their leaders and cut off the group's financing.
Speaking after meeting Asian leaders in Malaysia, he said: "Destroying (Islamic State) is not only a realistic goal, we're going to get it done."
"We will take back land they are currently in, take out their financing, hunt down leadership, dismantle their networks, supply lines and we will destroy them", he added.
Mr Obama also said it "would be helpful" if Russia directed its focus on tackling Islamic State and spoke of his hopes Moscow would agree to a leadership transition in Syria.
