At least 22 people were killed and more than 30 injured when a crane collapsed onto a passenger train in Thailand on Wednesday morning. The accident occurred in Sikhiu district of Nakhon Ratchasima province, about 230 kilometers from Bangkok, as the train was traveling from the capital toward the northeast. The crane, used in the construction of a high-speed rail line, suddenly fell onto one of the train’s carriages, causing it to derail and briefly catch fire.

Provincial police chief Thachaporn Chinnawong confirmed the death toll and said the injured were taken to nearby hospitals. Authorities reported that the fire was quickly brought under control and rescue operations began immediately after the incident.

Thai officials have launched an investigation to determine the cause of the collapse. The total number of passengers on board at the time of the accident remains unclear, according to police.
