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.

It’s not immediately clear what caused the explosion or how many children are among the victims.

The newspaper People’s Daily, which posted graphic photos and videos of the blast’s aftermath in Jiangsu province, reports that an investigation is now underway.

Shortly after the explosion, images began to circulate on social media, appearing to depict a chaotic scene strewn with bloodied bodies and bent metal. 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 of the injured remain in serious condition.

This is a developing story. Some things that get reported by the media will later turn out to be wrong. We will focus on reports from police officials and other authorities, credible news outlets and reporters who are at the scene. We will update as the situation develops.
