A tunnel collapse at the Coca Coda Sinclair hydroelectric project in Ecuador's Amazonian region has killed 13 workers and injured a further 12.
The incident occurred on Saturday evening, Ecuador's president Rafael Correa confirmed to news wires. Ten of the workers killed were from Ecudaor, with three from China. The cause of the collapse is being investigated.
The 1500MW Coca Coda Sinclair project is being built by China's SinoHydro, with the majority of funding for the scheme coming from the Export-Import Bank of China. The project includes construction of a dam and powerhouse on the Coca river and 24km of tunnelling work. The project is expected to come online in early 2016.
