Fires at a large chemical plant in the Chinese city of Shanghai have killed at least one person.
They broke out around 04:00 on Saturday at one of the country's largest refining and petrochemical plants.
Flames could be seen engulfing parts of the sprawling complex and spewing thick columns of black smoke into the sky.
The cause of the fires, which affected an ethylene glycol facility, is still unclear.
Sinopec - the state-owned company that operates the plant in the suburb of Jinshan - said the driver of a transport vehicle had been killed and a company employee had been injured.
The government said it is monitoring the environment around the site, and that so far the air and water bodies nearby are "primarily free of anomalies."
