Two people died and at least 18 others were injured after an explosion ripped through a four-story residential building in Madrid.
After an hour-long search, firefighters said the bodies of two workers – aged 21 and 27 – were found in the rubble.
The building, located in the upscale Salamanca neighborhood, was under construction at the time of the blast on Friday morning.
“Some work has been carried out on the building and the neighbors said there was a powerful explosion,” Madrid Mayor José Luis Martínez-Almeida told reporters.
The video released by the city of Madrid showed paramedics assisting the injured as police and firefighters sealed off the streets.
The blast sent plumes of smoke into the air and left nearby streets cluttered with glass and debris.
Four of the injured were taken to hospital, including a person in serious condition.
Spanish Prime Minister Pedro Sanchez said on Twitter who was following the situation closely and had offered his support to the victims.
“I am deeply sorry for the deaths of two young workers in the blast,” added Isabel Díaz Ayuso, president of the Madrid region.
“All our support and affection for their families and our eternal gratitude to the security and emergency services, especially the Madrid fire brigade”.
