Relatives of people who have gone missing in Pakistan's restive province of Baluchistan walk towards Islamabad, in Rawalpindi
Relatives of people who have gone missing in Pakistan's restive province of Baluchistan walk towards Islamabad, in Rawalpindi February 27, 2014. Relatives of rebels, activists and ordinary people who have gone missing in a lawless Pakistani province appealed to the United Nations for help on Thursday after a 2,300 km walk from Baluchistan which started last October, to draw attention to their plight. Bodies of hundreds of pro-independence rebels have been found across the Baluchistan province and many more have gone missing in the past several years, in a little-reported conflict in a remote corner on Pakistan's Iranian border.
