Spain is holding three days of mourning after two trains collided south of Madrid on Wednesday killing 69 people.

Rescue efforts: emergency service workers continue to search through the wreckage to find the missing people and identify any human remains. Spain's civil guard say they have deployed more than 900 people from specialist departments.

Leaked audio recordings: reveal the conversations between the train drivers and the control centre, which appear to show one high-speed train was given clearance to move even though another had stalled ahead.

Former minister killed: Spain's Employment Ministry confirmed that one of the people killed in the crash was 59-year-old former minister Fátima Báñez.

Spain's king visits crash victims: King Felipe VI has been visiting a hospital in Toledo where he has expressed condolences to those who have lost their loved ones, and has thanked the workers who are continuing rescue efforts.

A Spanish union boss has told the BBC that its workers "feel completely unprotected" following the train disaster.

Pedro Pevos, the national secretary of the independent trade union CSIF, says none of the union's workers "slept last night".

Asked about audio recordings of conversations between a control centre and train drivers which were leaked to Spanish media, Pevos calls the recordings "infamy".

"The mistake is really within the management. It is not something outside," he says.

The provisional death toll listed on the Spanish transport ministry website appears to have been revised back to 69.

It was previously listed as 74.
