A school roof collapsed in Pakistan, killing more than 30 children, the BBC reported on Thursday. The owner of the school has been arrested in connection with the incident, according to the BBC.
The collapse occurred in Peshawar, according to The Times of India. Early reports from other outlets gave lower tolls as the scale of the disaster became clear. CNN reported at least 28 children and one teacher were killed, while The Guardian put the figure at no fewer than 27 students. An earlier BBC report said at least 18 pupils and a teacher had died.
The varying numbers reflect how casualty figures shifted as more information emerged from the scene. The BBC's most recent count, published Thursday, put the death toll above 30 children.
The arrest of the school owner was confirmed in the BBC's reporting. No further details about the circumstances of the collapse or the owner's detention were available in the material reviewed.
Authorities have not yet released a full accounting of the dead and injured. What prompted the roof to give way remains unclear from the reporting available so far.
Officials are expected to release updated casualty figures and further details about the investigation.
