URUMQI - Nearly 100 children were injured Monday in a primary school stampede in Aksu City of northwest China's Xinjiang Uygur autonomous region, local authorities said.

Students of Aksu No 5 Primary School were heading downstairs to the playground for after-class exercise when some of them fell and triggered the stampede at 12:00 pm, a spokesman with the municipal publicity department, who declined to give his name, said.

The injured students were immediately taken to a local hospital. No death has been reported as of 2 pm, he added.

The school has more than 1,800 students.
