An explosion ripped through a kindergarten in eastern China on Thursday, killing at least seven people and wounding dozens more, according to the country’s state-run media. The blast hit the front gate of the building as parents and grandparents were picking up their children after the school day.
It’s not immediately clear what caused the explosion or how many children are among the victims — though Global Times, a state-run media outlet, cites a witness who blamed the explosion on a “gas cylinder at a roadside stall.”
Shortly after the explosion, images began to circulate on social media appearing to depict a chaotic scene strewn with bloodied bodies and bent metal.
“Videos purportedly shot in the aftermath of the explosion showed children and adults lying on the ground, many bleeding,” NPR’s Rob Schmitz reports from Shanghai. “Clothes, shoes and other items were strewn about beside pools of blood.”
Citing a statement by the Xuzhou city government, the South China Morning Post says two victims died at the scene and at least five others have died at the hospital, while nine of the injured remain in serious condition.
