Ten senior executives of the company that owned the warehouse site that exploded in the Chinese city of Tianjin have been detained, state media reported Tuesday, as authorities promised to investigate the cause of the disaster.
Li Liang, the president of Tianjin Dongjiang Port Rui Hai International Logistics Co, which stores and transports chemicals, was among those being held, as was the company's vice president, Cao Haijun, and Song Qi, the chief financial officer.
They have been under detention since August 13. Earlier reports had said two unnamed executives of the firm were in detention.
Massive explosions rocked the northeastern coastal city late Wednesday, killing at least 114 people, officials said, and devastating a large industrial zone and nearby residences.
At least 65 people are still missing, according to the latest figures from authorities.
Thousands of officials, firefighters, policemen and local residents mourned the victims at the blast site Tuesday, bowing their heads and observing a moment of silence to pay their respects.
China also said it was investigating the director of the country's work safety agency, Yang Dongliang, who was also Tianjin's vice mayor until 2012.
Yang was being investigated for "severe violation of discipline and law", the Chinese Communist Party corruption watchdog said, but didn't directly link the probe to the disaster.
