Investigators in China say preliminary enquiries have indicated that “human error” caused a pre-dawn crash between two high-speed passenger trains that killed at least 66 people and left hundreds of others injured.

The collision early on Monday took place near the city of Zibo in the eastern province of Shandong.

The accident left at least 400 injured, state media reports said, with at least 70 said to be in a critical condition.

It is the deadliest accident to hit China’s railways in more than a decade.
