A bomb blast near the eastern Chinese city of Ningbo has killed at least two people and injured dozens more.
The bomber struck shortly after noon in front of a factory in the Jiangbei district of the city, causing some nearby buildings to collapse.
State media reported that at least 30 people had been taken to local hospitals amid rescue operations.
Shots were taken by rescuers to transport people away from an area surrounded by debris.
Industrial accidents are common in China and have led to growing demands for better safety standards. The government says it has taken security measures. But while the number of workplace deaths in 2017 was reported to have fallen by more than 25% in 2016 - industrial deaths remain at least 29.000 a year to date.
Police say they have launched an investigation to determine the cause of the latest blast.
Chinese media reported that the blast occurred in an industrial area and that nearby damaged residential buildings were already empty due to the planned demolition.
Some local reports suggest that the gas bins could be to blame for the explosion.
Broken windows were reported in businesses up to 1 km away from the site of the explosion.
