Aakar Patel, executive director of Amnesty International India, said in a statement that the Jammu and Kashmir authorities must guard against any attacks, including reprisal attacks, which could lead to more civilian casualties.
"Shooting at a bus carrying ordinary people on a pilgrimage shows utter contempt for human life and the fundamental principles of humanity. Those behind this horrific assault should be found and punished," he said.
"The Jammu and Kashmir authorities must protect all civilians and ensure that they are not put in danger, while upholding human rights law and standards," Patel added.
