Around 91 young students are believed to be still trapped under the ruins of a collapsed school on Indonesia's main island of Java, National Disaster and Mitigation Agency spokesperson Abdul Muhari said on Tuesday (Sep 30). In a statement released late at night, Muhari revealed that the figure was based on student attendance data. Earlier in the day, officials said that at least three people had been killed, and 99 others were hospitalised, some of them with critical injuries. They further warned that the death toll could increase with dozens still trapped under the rubble.

Over 90 students trapped
According to National Disaster and Mitigation Agency spokesperson Abdul Muhari, "Based on student attendance data, 91 people are suspected to be buried under building materials."
How the collapse happened
Police say the students were performing afternoon prayers at the Al Khoziny Islamic Boarding School in Sidoarjo, East Java, in a building undergoing unauthorised expansion when it suddenly collapsed. While the female students praying in another section of the building reportedly escaped unharmed, the victims of the tragedy are mostly boys aged 12 to 17, studying in grades seven to eleven. Residents, teachers, and administrators helped evacuate injured students, many of whom suffered head injuries and broken bones.

Authorities are investigating the cause of the collapse. Provincial police spokesperson Jules Abraham Abast said the old prayer hall was originally two stories, but two additional floors were being added without a permit, likely contributing to the disaster.
Heavy concrete slabs and unstable parts of the building have hindered the search, with rescuers avoiding heavy machinery due to fears it could trigger further collapses. Several hundred personnel, equipped with breathing apparatus, extrication tools, and medical support, are involved in the ongoing rescue operation, according to an AP report.
