The head of the U.N. refugee agency says a "positive relationship between the Western and the Muslim worlds" is essential to overcome refugee crises like those facing Europe.

Antonio Guterres, the U.N. High Commissioner for Refugees, says there is an urgent need to fight fear of Islam and reduce the lure of extremist ideologies.

He told his agency's executive committee on Monday that financing has fallen short to handle "mega-crises" like those in Iraq and Syria and other crises in South Sudan, Burundi, Yemen and Libya.

He said "the humanitarian system is financially broke" and 33 U.N. appeals for assistance for 82 million people are 42-percent funded.
