A beachfront restaurant on the Spanish island of Majorca partly collapsed on Thursday, killing at least four people and injuring more than 20, officials said, with others feared trapped in the wreckage.

Photos predating the accident showed that the restaurant, Medusa Beach Club, had three levels, with large terraces on the middle and upper floors that were supported by pillars.

Video from the state-owned broadcaster RTVE and images from other news outlets appeared to show that at least parts of the terraces had collapsed down to the ground floor, and rescue workers in hard hats and reflective vests were picking through the debris to pull victims out.

It was not clear if any of the structure behind the terraces also fell in the collapse, which occurred about 8 p.m. local time.

Majorca’s emergency services said on X that four people were confirmed dead and 21 injured, but Spanish news outlets later said that officials had raised the number of injured to 27. Officials did not give the nationalities of the victims.

Prime Minister Pedro Sánchez wrote on X that he was closely following the recovery effort and had offered all the resources of the national government to local and regional leaders.

Majorca is the largest of Spain’s Balearic Islands in the Mediterranean Sea, popular resort destinations that are crowded much of the year with vacationers from northern Europe. Though it is separate from the region of Catalonia, many native islanders speak Catalan, which is an official language in the Balearics.

The Medusa, a restaurant and music venue, is in Playa de Palma, near Palma, the capital and largest city of the island chain. It sits on Calle de Cartago — Carthage Street — facing the Bay of Palma.
