Violent extremism is not limited to a specific region or religion, UN Secretary-General Ban Ki-moon said on Wednesday in a speech at the closing session of the Madrid + 10 Counter Violent Extremism meeting."Violent extremism is a diverse phenomenon. It is indeed no exclusive to any one region or system of belief. Violent extremism which breeds terrorism poses a direct assault on the UN charter, the United Nations universal declaration of human rights and values on which the United Nations was founded. It affects all areas of the world of the United Nations. It undermines international peace and security and threatens to reverse important developments of progress," he said."Now we have 60 million refugees around the world. This is the largest ever since the end of the Second World War. We have four and a half million Syrian refugees and hundreds of thousands people fleeing their countries now. European countries, all of them, without almost exception, they are now struggling to handle these issues. Countering this threat through effective security responses should remain a priority," he said.The two-day meeting is aimed at creating a document titled the "Global Consensus" in which officials will share their vision of values and principles that stand the best chance of achieving real progress in the struggle against extremism.
