Ban has also announced that the world body has signed an agreement with Saudi Arabia, which will donate $10 million for a UN Center for Counterterrorism in New York.

Ban told UN member states on Monday that countries realize they cannot fight the battle alone.

The UN chief is highlighting the resolve shown by countries five years ago when they adopted the UN Global Counterterrorism Strategy. That document recognizes terrorism cannot be fought by law enforcement alone and requires a combination of social, educational, economic and political tools.
