Beijing: Chinese authorities said they have identified 10 senior executives they believe are responsible for the warehouses involved in explosions nearly a week ago in Tianjin, shortly after the national anti-corruption agency announced it was investigating the head of the country's work safety regulator.

The announcements came amid mounting anger over the blasts, which killed 114 people and injured more than 700 the night of August 12. The government has promised a transparent investigation into the explosions, which left a massive crater in an industrial zone and raised fears of chemical contamination in the surrounding residential area. Authorities say that at least 57 people are still missing.

According to the state-owned newspaper Tianjin Daily, Yu Xuewei, chairman of the Dongjiang Port Rui Hai International Logistics Company, was detained along with the vice chairman Dong Shexuan, on Thursday, several hours after the blasts.
