Searchers yesterday raced to rescue at least 38 people still believed trapped a day after the collapse of an under-construction Islamic school building in Indonesia that has already left three dead, authorities said. Tearful families desperate for news of their loved ones crowded around the flattened multi-storey building, as rescuers navigated a maze of concrete rubble in the town of Sidoarjo on Indonesia's main Island Java. The building gave way on Monday, where students were gathered for afternoon prayers, said local reports, citing a witness. National Disaster Mitigation Agency (BNPB) spokesman Abdul Muhari said 38 people were still unaccounted for while 77 injured victims had been evacuated to several hospitals.
