Hundreds of protesters have gathered at Jantar Mantar, in the heart of the national capital, to mourn the 23-year-old gang-rape victim who was cremated here on Sunday morning. Police have imposed prohibitory orders around India Gate and Raisina Hill and barricaded all roads leading to the area, as well as shutting down 10 Metro stations in central Delhi. Comprising mostly students, the protesters are demanding tougher anti-rape laws.
