The Vishwa Hindu Parishad (VHP) sponsored ‘panch kosi yatra’, a religious march, began on Monday amid tight security, police officials said. Security forces have been put on high alert around the temple town of Ayodhya and section 144, which prohibits unlawful assembly, is in place, said officials who added only seers and saints would be allowed to participate in the ritual. Unlike the ’84-kosi Parikrama’ in August when the state government banned the ritual and arrested hundreds of saints and VHP activists, this time no preventive arrests have been made, an official told IANS. The official added the security personnel have been asked to maintain peace at all costs. The formal start of the ritual was done Sunday at the Karsevakpuram by the holding of a ‘yagna’.
