Four Americans and one Canadian were among the 69 people killed in a high-speed train collision in Spain last Wednesday, authorities confirmed Sunday. Of the 69 deceased, 66 have been identified so far. Most of the victims were Spanish nationals.

Other foreign nationals among the dead include one each from France, Japan, Argentina, Mexico, Portugal, Tunisia, and the Czech Republic. Two Australians and one Japanese national remained missing, according to authorities.

The crash occurred in the province of Toledo when a high-speed train slammed into another train that had stopped on the tracks. The incident has raised concerns about the safety of Spain's rail network, which has been praised for its speed and safety record. This collision follows another on the same Madrid-Seville line nine months prior, which resulted in 46 fatalities.

Prime Minister Pedro Sánchez has pledged an investigation into the crash and committed to implementing improvements to restore public confidence in the rail system, which transports approximately 45 million passengers annually, including millions of tourists.
