Shanghai chemical leak 'kills 15'
An investigation is underway into a chemical leak that killed 15 people in China's commercial hub of Shanghai, according to China's official news agency.
Dozens of others remain ill and eight of them are in a critical condition after exposure to liquid ammonia from a cold storage unit.
Officials say the cause of the leak at Weng's cold storage industrial company is still not clear.
