Title: Pakistanis in Kyrgyzstan

There are 200 Pakistani students in Kyrgyz State Medical Academy alone.  They have complained to the media about the poor treatment they face at the hands of local "militsiya".  During the 2010 South Kyrgyzstan riots, fifteen Pakistani students were taken hostage by militants in Osh, among whom one, a final-year engineering student named Ali Raza was killed.  Another 263 were evacuated from the city.  Students in unaffected areas were not evacuated and remained in the country.  Later that year, Pakistani businessman Zahid Jan of ZTK Co. announced plans to invest in Jalal-Abad with the construction of a juice factory there.
