Hundreds rescued after fire breaks out in Tokyo school

Firefighters rescued one teacher and several schoolchildren with non-life-threatening injuries, the department said.

Television footage showed black smoke billowing out of windows on the fourth floor, as firefighters combated the blaze. 

Dozens of fire engines were deployed.

All others inside the building when the fire broke out had evacuated to a nearby park on their own and no one was left behind, officials said. 

The cause of the fire is still under investigation.
