SIDOARJO, Indonesia (AFP): Around 91 people are believed to be still trapped under the ruins of a collapsed school on Indonesia’s main island of Java, authorities said as rescue teams searched for survivors. The multi-story Islamic boarding school in the town of Sidoarjo suddenly gave way on Monday as students were gathered for afternoon prayers, according to local reports. Officials said Wednesday they were still trying to confirm the number of missing when asked at a news conference in Sidoarjo. Rescue teams were focusing on supplying life support to survivors trapped under the rubble, said Emi Freezer, the National Search and Rescue Agency’s head of operations. “The main structure has totally collapsed … We prioritized saving victims who were still responsive.”Dozens of parents waited Wednesday near the collapsed school building as rescue teams searched for survivors under the rubble.
