Real Madrid’s Bernabeu Stadium appears to have caught fire on Wednesday night, with firefighters being called to the scene.
It is not known what caused the fire or whether anyone has been injured.
Huge plumes of thick black smoke filled the skies above the famous old stadium as emergency vehicles sped to the scene.
Huge flames could be seen burning inside the stadium through one of the exposed parts of the construction.
Some people were reporting on social media that the flames could be seen from vantage points in various parts of the city.
Madrid was granted permission to begin the major construction operation – which is due to be completed for the start of the 2022-23 season – at the 73-year-old venue in March.
Bizarrely, all the works will actually REDUCE the final capacity by one seat.
Amongst the changes, there will be a fully retractable roof and even a 360-degree video screen that stretches around the entire ground.
