Authorities, who declared three days of mourning, gave no immediate indication as to the cause but said the excessive weight of the building was most likely to blame.

The packed two-storey building housing Beach Club Medusa collapsed late on Thursday afternoon in the Playa de Palma area south of the capital with the tourist season already in full swing in the Balearic Islands, which also includes Ibiza and Menorca.

“There are four dead and 16 injured,” an emergency services spokeswoman said, lowering the initial toll from around 21 injured.

Seven people were injured “very seriously” and nine were seriously injured, emergency services said on the X social media platform. They were taken to various hospitals in the Mediterranean island’s capital, Palma de Mallorca.

Firefighters were deployed in number, ambulances rushed victims to hospital and the street was sealed off by police to allow rescue teams to work, an AFP journalist saw.

One firefighter described a “nightmarish” scene.

He told the Ultima Hora newspaper that when he arrived, people were crying and screaming around the rubble piled up on the ground floor.

Rescuers pleaded for silence so they could listen out for people who could be trapped under the rubble.

The head of the Palma fire service, Eder Garcia, said the street-level floor of the building had collapsed onto a bar in the basement, which is “where we found the most victims”.

“The causes are being investigated. The first hypothesis is that it was possibly due to excessive weight,” he told reporters at the scene.

The four people killed in the collapse of a beachfront restaurant on Spain’s holiday island of Mallorca were two German tourists, a Senegalese man and a Spanish woman, police said on Friday.

“The victims are two German women aged 20 and 30, a 23-year-old Spanish employee and a 44-year-old Senegalese man,” a police spokesman told AFP.

A technical team was due to visit the site on Friday to determine the cause of the collapse of the building, which sits on Calle de Cartago facing the Bay of Palma.

‘Terrible collapse’

Spanish Prime Minister Pedro Sánchez conveyed his condolences to the victims’ families on X, saying he was “closely following the consequences of the terrible collapse”.

The central government was prepared to send “all the necessary resources” to help the regional authorities cope, he added.

Sanchez said he had spoken to the governor of the Balearic Islands region, where Mallorca is located, and to the city’s mayor.

Balearic Islands president Marga Prohens said on X that she was “shocked” by the news, adding she was sending “love and warmth to the families of the four people who have lost their lives”.

Mallorca is known for its pristine waters and beaches, and the Balearic Islands attract more tourists than all Spanish regions after Catalonia.

More than 14 million tourists visited the islands last year, according to official figures.

Thursday’s collapse took place at the start of the archipelago’s peak tourist season, on a beachfront avenue home to several shops and entertainment venues.

The 2009 collapse of a three-story building in Palma de Mallorca killed seven people, including three Colombians and two Germans.
