Dozens of students presumed buried under rubble of school in Indonesia

SIDOARJO, Indonesia - At least 65 students were presumed buried under the rubble of an Islamic school building that collapsed in Indonesia. 

According to The Associated Press, rescuers ran oxygen and water to students trapped in the unstable concrete rubble of the collapsed school building, as they worked to free survivors Tuesday morning, more than 12 hours after the structure fell.

What we know:

At least one student was killed, dozens were injured and 65 were presumed buried in the rubble. The students were mostly boys in grades seven to 11, between the ages of 12 and 17.

Rescue workers, police and soldiers pulled out eight weak and injured survivors more than eight hours after the collapse at Al Khoziny Islamic Boarding School in the East Java town of Sidoarjo. Rescuers saw additional bodies, indicating the death toll was likely to rise.

The students had been performing afternoon prayers in a building that was undergoing an unauthorized expansion when it suddenly collapsed on top of them, provincial police spokesperson Jules Abraham Abast said.

Families of the students gathered at hospitals or near the collapsed building, anxiously awaiting news of their children.

What they're saying:

"We have been running oxygen and water to those still trapped under the debris and keeping them alive while we work hard to get them out,"Nanang Sigit, a search and rescue officer who was leading the effort, told AP. 

Several hundred rescuers were involved in the effort and had equipment for breathing, extrication, medical evacuation and other support tools.

What we don't know:

Authorities were still investigating the cause of the collapse.

"The old building’s foundation was apparently unable to support two floors of concrete and collapsed during the pouring process," Abast said.
