Spanish Prime Minister Pedro Sanchez announced three days of national mourning following a high-speed train crash in Adamuz, near Córdoba, that killed at least 40 people and injured more than 120. He said authorities would get to the bottom of why two high-speed trains collided as rescuers continued searching the wreckage. Rail operator Adif said the collision occurred at 19:45 local time on Sunday, about an hour after one train left Málaga for Madrid, when it derailed on a straight stretch of track and crossed onto the opposite line, hitting an oncoming train. Transport Minister Óscar Puente said the impact pushed carriages of the second train into an embankment and that most casualties were in the front carriages of the second train, which was traveling from Madrid to Huelva. Rescue teams reported that twisted wreckage made it difficult to reach people trapped inside.
