By Saad Sayeed and Mubasher Bukhari CHAKWAL, Pakistan, May 25 (Reuters) - In a cluster of villages in Pakistan's largely rural Chakwal district, more than 100 Shi'ite Muslims have returned from the United Arab Emirates without jobs, luggage or access to the savings they spent years building abroad. They are among potentially thousands of Shi'ites deported from the UAE to Pakistan during the Iran war, raising alarm in Pakistan's Shi'ite community and prompting Human Rights Watch to investigate.
