New Delhi, Nov.11 Senior BJP leader and the Leader of Opposition Lal Krishna Advani on Wednesday stressed on the need to develop mutual cooperation between countries to root out terror.

Addressing a school function participated by students from India and abroad, including Pakistan, Advani said: "There is mutual agreement between countries to extradite people who have committed any crimes in this country or escaped to another country. All these agreements have been of great help in cooperation in a matter of dealing with terror. And I wish India could have such treaties with every country of the world represented here."

India has witnessed a series of terror attacks in the recent years, with the major one being in Mumbai last November, which left at least 166 dead. (ANI)
