Organised by the New York-based Sikh for Justice (SFJ), separatist Sikhs protested against the alleged constitutional denial of the Sikh religion and human rights violations.
"The Indian Constitution subjects Sikhs to Hindu laws; We will not allow religious persecution to continue and will pursue the right to self-determination for the Sikhs," alleged SFJ legal advisor Gurpatwant Singh Pannun.
"Sikhs have right to referendum and Indian government must abide by UN Convention on Civil and Political rights," he said.
