China chemical leak in Shanghai 'kills 15'
A chemical leak of liquid ammonia from a cold storage unit in Shanghai has killed 15 people, according to China's official news agency.
There were also 26 people injured in the leak at around 11:00 local time (03:00 GMT), Xinhua reports.
Local media published pictures of firefighters at the scene.
China's industrial safety regulations are sometimes ignored by local authorities focused on boosting economic development, observers say.
