Led by Sena's state senior Vice-President Rajesh Palta, the protesters demanded immediate resumption of the Amarnath Yatra, which had been suspended due to "chaotic conditions" in Jammu and Kashmir, police said.
The protesters started from Hanumangarhi Temple and converged on National Highway 1, blocking its two sides, leading to long queues of vehicles towards Jalandhar and Ludhiana, they said.
Raising slogans against Narendra Modi government and PDP government, they demanded dismissal of J&K government and imposition of President's Rule there. They also burnt a poster of Chief Minister Mehbooba Mufti, police said.
In view of the protest, the Delhi-bound Sada-e-Sarhad bus from Lahore was diverted via Kartarpur, Kapurthala, Nakodar, Noormahal, Phillaur onto the NH 1. Lahore-bound bus coming from New Delhi was also diverted from Phillaur, Noormahal, Nakodar, Kartarpur onto the NH 1.
