At least 32 people were killed and 64 others injured Wednesday when a construction crane fell onto a moving passenger train in northeastern Thailand.

The derailment occurred on part of an ambitious planned high-speed rail project that will eventually connect China with much of Southeast Asia.

The crane, which was being used to build an elevated part of the railway, fell as the train was traveling from Bangkok to Ubon Ratchathani province, according to the public relations office for Nakhon Ratchasima province, where the accident took place.

Photos published in Thai media showed plumes of white, then dark smoke above the scene and construction equipment hanging down from between two concrete support pillars.

Rescue workers stood on top of overturned railway carriages, some of them with gaping holes torn on their sides, video from public broadcaster ThaiPBS showed. What appeared to be sections of the crane were scattered along the track. Meanwhile, paramedics gave first aid to injured passengers.
