A blast at a fireworks factory in China's Hunan province has killed 21 people and left 61 wounded, according to state media.
The explosion at the Changsha Liuyang Huasheng Fireworks plant happened at around 16:40 local time (08:40 GMT) on Monday, in the city of Liuyang, leading rescuers to evacuate everyone within a 3km (1.9mi) radius of the plant.
Authorities deployed nearly 500 personnel to conduct search and rescue operations and treat the injured, while robots were used to help find those trapped within the building.
Police, who are investigating the cause of the blast, have taken "control measures" against the person in charge of the fireworks company, Chinese state media reported.
Authorities said that two gunpowder warehouses within the factory area posed a high risk amid rescue efforts, state media reported.
