On December 16 , 2014 , there was a terrorist attack on a school in Peshawar by the Pakistani Taliban group Tehreek-e-Taliban ( TTP ) , the leaders of which are claimed to be based in Afghanistan in areas outside of Kabul control according to senior Pakistani officials . The attack killed at least 145 people , most of them school children . Following the attack , the Pakistani government adopted the National Action Plan ( NAP ) to tackle terrorism and one of the 20 points of this action plan was to establish a comprehensive policy to register Afghan refugees . Since 2015 , there have been reports of Afghan refugees in Pakistan encountering serious harassment , hostility , and pressure to return to Afghanistan . There has been an ongoing exodus of tens of thousands of refugees as of February 2015 . According to the Human Rights Watch , in 2016 there were about 365,000 documented and 200,000 undocumented Afghan refugees repatriated from Pakistan . The mass exodus has been described as voluntary repatriation by the Pakistan government as well as UNHCR , however in a recent report the Human Rights Watch described it as unlawful coercion of Afghan refugees and voluntariness of return has been questioned
