School books lie on the ground after a blast near a school in Brindisi on May 19, 2012. A 16-year-old girl died Saturday after a powerful bomb blast outside their school in the southern Italian city of Brindisi, with another seven injured, one critically. No one has claimed responsibility for the blast caused by gas canisters hidden in a container or backpacks placed near a wall of the school grounds, according to initial indications.
