Amid a renewed debate over the proposed withdrawal of the Armed Forces Special Powers Act (AFSPA) from certain parts of the State, Kashmir Valley was rattled on Tuesday by at least four grenade attacks on security forces at different places within a span of four hours. The attacks, coming just four days after Chief Minister Omar Abdullah announced his intentions of removing the controversial Act from at least four cities, including Srinagar, Budgam, Jammu and Samba, have only gone on to back the Army and Defence Ministry’s opposition to the proposed move primarily on the ground that such “enclaves” where the Act is not applicable will embolden the ultras to take shelter there.
