After days of refusing to bury those who died in Saturday's deadly sectarian bombing, the first funerals have begun and hundreds of Hazara Shia mourners came to pay their last respects at a cemetery outside Quetta. Their grief mixed with anger after the four-day protest didn't end with a government promise to deploy the military to go after the groups responsible for attacking them. Shots were fired in the air by security forces after some protesters pelted them with stones and also returned fire - many mourners ran for cover while others stayed behind, determined to bury the dead.
