A grenade exploded at a zoo on the outskirts of Sri Lanka's capital on Sunday, wounding four people as fierce battles between soldiers and Tamil Tigers in the restive north left 27 insurgents dead, Associated Press quoted the military as saying. The attack took place in the bird sanctuary at a zoo in Dehiwela, a suburb of Colombo, military spokesman Brig. Udaya Nanayakkara said, adding it was not clear who was behind the latest blast or their motives.
