At least seven people were killed and 59 others were injured in an explosion at the entrance of a kindergarten in eastern China on Thursday, city government said.
The blast struck the school in Fengxian, located in Jiangsu province, at 4:50 p.m. local time, police said. Officials are investigating the incident.
It’s unclear how many children were among those killed and injured. Videos and photos from the scene showed people, including children, lying on the ground, with some covered in blood, according to the South China Morning Post.
It’s unclear if the explosion was deliberate, though an unidentified witness told local newspaper Xiandaikuaibao that the bomb appeared to be a cooking gas.
Kindergartens in China have been targeted before in apparent revenge attacks carried out by people bearing grudges against their neighbors and society.
