Four US citizens and one each from Canada, Japan, Argentina, Mexico, Tunisia and the Czech Republic were among the 69 people killed in last week's high-speed train collision in Spain, authorities said.

A legal body set up to handle identification, made up of police and forensics experts, announced the 10 latest confirmed foreign victims in a statement late on Sunday. It had already announced the deaths of a French and a Portuguese citizen, as well as 54 Spaniards. All but three victims are now identified, the statement said.

Three missing-person reports remain active, concerning two Australians and one Japanese citizen. The statement said the contacted families want to travel to Spain for in-person identification and that authorities are awaiting their arrival.

The collision occurred when a Renfe service ploughed into the back of a stationary Iryo train outside Urda, about 130 km (80 miles) south of Madrid, according to the report. The report says a failure of an automatic safety system halted all trains on a 63 km stretch of track, but a control centre authorised the Renfe service to resume its journey while the other train was still stationary.

The accident was Spain's second high-speed train collision this year. A crash in Andalusia in January killed 46 people, according to the report, which says the latest disaster raised fresh questions about the country's rail safety. The collision took place one month before a 29 November general election in which Socialist leader Pedro Sánchez will seek to extend his eight-year premiership.
