Islamabad/ Peshawar, Feb 07 (ANI): Pakistan said it wanted the Afghan government and the United Nation's refugee agency UNHCR to encourage Afghan refugees still living in Pakistan to return to their homeland as soon as possible. According to UNHCR country profile for 2015, Pakistan still hosts almost 1.5 million registered Afghan refugees, the largest protracted refugee population globally, that have fled decades of conflict in neighboring Afghanistan. Since 2002, UNHCR has facilitated the return of 3.8 million registered Afghans from Pakistan. Pakistan Foreign Ministry Spokesperson Tasnim Aslam said the main group of 'people of concern' was the unregistered refugees who, because of their illegal status, could easily fall prey to terrorists.
