|Hebron mayor Kamel Hmaid visited the children in hospital Wednesday.|
Dr Jihad Shawer, who runs the emergency unit at Hebron hospital, said 29 children were admitted. Some were treated for fractures.
The incident occurred during a drill led by the civil defense at Al-Arrub elementary school.
Students told Ma'an they were instructed to evacuate their classrooms in an orderly manner when the school's bell rang. But dozens of children were trampled as they ran to the playground, students said.
Some of the children "left in a hurry and fell on top of each other," a student told Ma'an.
Hebron mayor Kamel Hmaid, who visited the injured children in hospital, said an inquiry committee had been formed to investigate the accident. He said the incident underscored the need for disaster training.
