ISLAMABAD, Feb 19: A Pakistan police spokesman said on Friday a case has been lodged against unnamed perpetrators of a deadly attack on an Indian air base last month that has renewed tensions between the rivals. The Jan. 2 attack on the Pathankot air base, in which seven Indian security personnel were killed, has stalled hopes of revived peace talks between the nations after Indian Prime Minister Narendra Modi made a surprise visit to his counterpart Nawaz Sharif in December.      ?REUTERS
