A biotech company in Lianyungang, Jiangsu province, where an explosion claimed 10 lives in December, has been fined 5 million yuan ($730,750). Its production permit will be revoked and its leaders will be prosecuted, the Ministry of Emergency Management said.

The energy released by the blast was equivalent to 14.15 metric tons of TNT, according to the investigative report by the Jiangsu government.
