In January 2008 , BBC reported that about 6,000 Pakistanis from Khyber Pakhtunkhwa crossed into Afghanistan , which included women and children . While fighting in northwest-Pakistan between the Pakistani Armed Forces and the Pakistani Taliban may have been one reason , Sunni Shia sectarian strife was also suggested as a possible driver for their flight . They were able to receive medical aid in Khost and Paktika provinces . By September 2008 , their number had reached 20,000 , and about 70 % of the refugees were Pakistanis while the rest were Afghans who had settled in Pakistan during the last 20 or so years . More Pakistani refugees went to Afghanistan after the 2010 Pakistan floods . As of 2015 , around 221,432 Pakistanis are found living in Afghanistan . Most of them are in Khost Province and Paktika Province . There are also a small number of Pakistani Baloch migrants , mainly concentrated in the southern parts of Afghanistan like Nimruz
