China’s district courts have handed jail terms to two fire chiefs and two poultry farm bosses over their roles in a fatal fire in north-eastern China last year.

The blaze killed 121 people and injured 76 others in a June 2013 fire in Jilin province.

Survivors at the time described workers, mostly women, struggling through smoke and flames in the poultry processing plant to reach doors that turned out to be locked or blocked.
