U.S. President Barack Obama on Sunday said the United States and its allies would not relent in the fight against >Islamic State extremists and would hunt down their leaders and cut off the group's financing.

“Destroying [Islamic State] is not only a realistic goal, were going to get it done,” he said ata a news conference after a meeting of Asian leaders in Malaysia.

“We will destroy them. 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.”
