Terrorism and extremism are "common concerns" and Saudi Arabia will extend all cooperation to India and other neighbouring countries to deal with them, Saudi Crown Prince Mohammed Bin Salman said on Wednesday after holding "extensive and successful" talks with Prime Minister Narendra Modi.

The talks took place a day after the influential Arab leader concluded a high-profile visit to Islamabad, and in the backdrop of India's escalating tension with Pakistan following the Pulwama terror attack.
