Spain begins three days of mourning after train collision kills 69

Spain has begun three days of national mourning after a high-speed rail disaster in which one train struck another from behind, killing 69 people. It is the second disaster of this scale involving high-speed trains in the country this year.

The crash has renewed concerns about the safety of Spain's rail network. These questions arise as the country approaches a national election, which makes rail safety a pressing subject of public debate.

The source does not give details on the exact location of the crash, its causes or the number of injured, so these circumstances are not yet known.
