New Delhi: The Supreme Court will pronounce its historic verdict on a batch of a petition against the 2010 Allahabad High Court order in the politically-sensitive Ramjanmbhoomi-Babri Masjid land dispute case Saturday morning. Prime Minister Narendra Modi has appealed for calm ahead of the verdict as security has been beefed in Uttar Pradesh especially in Ayodhya. School and colleges are shut in Uttar Pradesh, Karnataka, Jammu and Kashmir, Madhya Pradesh and Delhi and prohibitory orders have been clamped in several places across the country.
