SRINAGAR: Police have arrested a prominent rights activist in India-held Kashmir a day after he was barred from leaving India to travel to Geneva to participate in a session of the United Nations’ Human Rights Council, police and family members said on Friday. Police picked up Khurram Parvez from his home in Srinagar late on Thursday night. A police officer, speaking on condition of anonymity, gave no details about the possible charges against Parvez. On Wednesday, immigration officials at New Delhi’s international airport barred Parvez from boarding a plane to Geneva, even though he had a valid visa and letter of invitation from the UN body. Parvez and his organisation, the Coalition of Civil Society, were the first to report and draw attention to thousands of mass graves in remote parts of Kashmir and to demand that the government investigate them so as to make clear who the dead were and how they were killed.
