Several activists of the Shiv Sena today burnt the Pakistani flag in Phagwara, Punjab, to protest the "Pak-sponsored" terror attack at Dina Nagar area of Gurdaspur district. The protest, led by the party's state Vice President Inderjit Karwal, prompted authorities to divert the route of one of the buses plying between India and Pakistan under the banner of "Sada-e-Sarhad".
