NEW DELHI- Home minister Rajnath Singh today blamed Pakistan for terrorism within India during the Hindustan Times Leadership Summit in Delhi. Singh’s address comes at a time when the National Investigation Agency is investigating a blast in West Bengal's Burdwan district. He said India wants to maintain cordial relations with Pakistan but Islamabad seems not too keen on establishing friendly relations with New Delhi.  "Terrorism in India is Pakistan sponsored. ISI is aiding terrorism," he said. Blaming Islamabad for sponsoring terrorism in India, he said the neighboring country is providing shelter to Dawood Ibrahim and the mob boss is currently staying along the Pak-Afghan border.
