At least 13 people were killed and several others were injured when a fire early Sunday ripped through adjoining nightclubs in Spain, authorities said.

Iran PressEurope: At least 13 people have been killed in a fire in a Spanish nightclub, authorities say, with fears the toll could still rise as rescue workers sift through the debris.

Emergency services said that the fire ripped through adjoining nightclubs in Murcia in southeast Spain on Sunday, adding that rescuers were still searching for people unaccounted for after the blaze.

Jose Ballesta, mayor of Murcia, said the fire had broken out at around 6 a.m. local time (04:00 GMT) and was “extremely serious”.

Ballesta told reporters at the scene “There are still bodies to be pulled out” from the rubble, which he said was complicated given the “risk of collapse”.

Video released by Murcia Fire Service showed firefighters working to control flames inside the nightclub. The footage also showed part of a roof collapsing.

The identification of the bodies would take time, Seral said. The emergency services gave the death toll, which has risen steadily throughout the day, as 13. The cause of the blaze is being investigated.
