No cause has been given for the collapse of the building.
Palma Beach is a busy resort area of the Mallorcan capital with a large number of bars and nightclubs, popular with German and British tourists.
According to local reports, both the upper floor and the ground floor of the restaurant collapsed down onto the building’s basement.
Four people are confirmed to have died, with seven described as very seriously injured and nine more seriously injured.
The injured were taken to various hospitals in the Palma area.
Raul Pursnami, owner of a fashion store next to the affected premises, was quoted by the Spanish newspaper El País as saying that a loud noise accompanied the collapse. “I was leaving the premises and everything has fallen down, it’s a shame.
“Theoretically, an inspection has to be done every year. We are terribly affected; I can’t talk, they were my neighbours.”
