This story is on both sides of the border. There could be multiple reasons, but, one of the main reason in my view is to attract the majority people of majority sect, the Hindu in India and Sunni in Pakistan for political objectives. Passengers traveling to Gilgit, armed people came and stopped their busses, off loaded passengers to identified them to ensure if they are Shia and then killed. As we speak no culprit punished for this crime. Therefore sectarian ideologies for political objectives, in my view, become poison to both countries and minorities in India and Pakistan.
