The three-storey building at Al Khoziny Islamic boarding school in Buduran, Sidoarjo, East Java, collapsed on September 29 in the afternoon, local authorities said. Rescue operations remain underway with more victims feared trapped, Tempo reports.

The incident occurred around 3pm while students were performing afternoon prayers on the second floor, which was being used as a prayer hall. The structure, still under renovation, had undergone fresh concrete work on its roof earlier that day, said the school’s caretaker Abdul Salam Mujib.

“Poured concrete was applied from morning until noon, and by the afternoon the roof suddenly gave way,” Mujib told reporters. He added that the project had been under renovation for about nine months, with plans to complete a three-storey dormitory topped with a cement roof.
