KUALA LUMPUR, Nov 22 (Reuters) - The United Nations Secretary General Ban Ki-moon said on Sunday that he has urged Russia and the United States to cooperate on rooting out terrorism.

"All these terrorists and ideology extremists should be defeated in the name of humanity," he said at the annual East Asia Summit this year hosted in Kuala Lumpur.

"In that regard, we need to unite. We need to show global solidarity to address the common enemy of ISIL, Daesh, some other extremists and terrorist groups," he said, referring to Islamic State.

U.S. President Barack Obama said at the same summit the United States and its allies would not relent in the fight to combat Islamic State extremists and would hunt down their leaders and cut off the group's financing.

Russian President Vladimir Putin said on Saturday he wanted global cooperation to combat terrorism after Islamist militants killed 19 people, including six Russians, in an attack on a luxury hotel in Mali. (Reporting by Denis Dyomkin; writing by Praveen Menon; Editing by Bill Tarrant)
