Four people have been detained in connection with the chemical pipeline explosion in Nanjing, which killed 13 people. AFP reports:
More than 300 others were injured in the blast on Wednesday, which occurred on the grounds of an abandoned plastics factory in Nanjing, capital of Jiangsu province, as workers were demolishing the facility.
The explosion reportedly occurred when a pipeline carrying ethylene gas was damaged while workers using diggers were dismantling buildings and retrieving parts that could be resold, Xinhua news agency reported.
The leaking gas was ignited when a nearby motorist started their car engine, according to the local work safety administration.
Police have arrested three construction contractors and a factory official responsible for work safety at the site, Xinhua said.
