New Delhi: Prime Minister Narendra Modi Thursday said the "expanding footprint" of extremist and terrorist organisations in Pakistan and their links with terror activities in India was a major security challenge.

Addressing the concluding session of the conference of governors at Rashtrapati Bhavan, the prime minister said ceasefire violations were continuing along the Line of Control. According to a statement from the Prime Minister's Office, Modi said the government had moved away from the model of "one-size-fits-all" schemes and was working towards cooperative, competitive federalism through the NITI Aayog.
