SIDOARJO, Indonesia (AP) — Rescuers ran oxygen and water to students trapped in the unstable concrete rubble of a collapsed school building in Indonesia, as they desperately worked to free survivors Tuesday morning more than 12 hours after the structure fell. At least one student was killed, dozens were injured and 65 were presumed buried in the rubble. Families of the students gathered at hospitals or near the collapsed building, anxiously awaiting news of their children. Relatives wailed as they watched rescuers pull a dusty, injured student from a buried hall. Residents, teachers and administrators assisted injured students, many with head injuries and broken bones.
