A liquid ammonia leak from a refrigeration unit at a facility in China's commercial hub of Shanghai has killed 15 people, the official Xinhua news agency has reported. A further 26 people have been sickened.
More than a dozen people were reported to have died on Saturday following the leak from a refrigeration unit at a cold storage facility in Shanghai's northern district of Baoshan.
According to Xinhua, the incident occurred at 10:50 a.m. local time (02:50 GMT) at Shanghai Weng's Cold Storage Industrial Co. Ltd. It did not give any further details.
Six of the 26 people injured remain in a critical condition, news agency Reuters has reported, citing government sources.
The cause of the leak remains unknown.
China has a poor record on workplace safety and industrial accidents are common.
In June, 120 people died and dozens more were injured following a fire at a chicken processing plant in China's northeastern Jilin province.
