Many children were hurt at a primary school in Berlin after someone used tear gas.
37 students are now showing symptoms of being affected by the gas at Miriam Makeba School.

Authorities evacuated the school and closed it down shortly after 9am today due to the incident.
Affected pupils are reportedly being treated by emergency services at the scene.
Tear gas was sprayed in the hallway of the school building, local media has reported.
Students affected complained of shortness of breath and eye irritation.
A fire department spokesperson told local media that 37 children were affected.
“One child had to be transported to a hospital for further medical care,” they added.
A police spokesperson said that the building has been ventilated and there is no further danger to students and teachers.
It comes following another incident in Germany at a school in Dresden last year.
As many as 38 children were injured in a horror gas attack at a school.
It was reported that an “irritating gas-like substance” was sprayed at the school.
A spokesperson for the fire brigade said: “We have triggered a major alarm and prepared the clinics in Dresden and the surrounding area.”
Numerous children were complaining of breathing difficulties, irritated eyes and intense coughing.
