ISLAMABAD: Law enforcement and intelligence officials on Sunday visited several religious seminaries in and around Rawalpindi and Islamabad and collected information on the students, particularly of foreign origin, studying there. The officials also visited International Islamic University and National University of Modern Languages and collected information on foreign students, particularly Uzbek and Tajik nationals, sources told Daily Times. Seminary students were asked about their backgrounds and the seminaries' administrators were also inquired in this regard, sources added. Law enforcement and intelligence officials also visited the students' living quarters and searched them for weapons and objectionable material, but found none.
