India is committed to efforts to develop its restive territory of Jammu and Kashmir, Prime Minister Narendra Modi said on Friday, accusing neighbour Pakistan of seeking to destroy livelihoods there with April's deadly attack on tourists.

Indian Prime Minister Narendra Modi arrived in Kashmir on Friday, his first visit to the contested Himalayan region since a conflict with arch-rival Pakistan last month, and opened a strategic railway line.

Modi visited the Chenab bridge on Friday with tight security, waving an Indian tri-colour flag before boarding a test train that passed through picturesque mountains and tunnels to reach an inauguration ceremony for another high-elevation bridge named Anji.
