At least 40 revellers were injured when the dancefloor of a nightclub in Tenerife collapsed.
Clubbers fell through the floor to the basement of the Butterfly Disco Pub at about 2.30am on Sunday morning.
Several people suffered broken bones, including leg fractures.
The club is in a shopping centre in Playa de las Americas in the south of the Spanish island popular with tourists.
Those injured are said to be from a number of different countries, including the UK, Spain, France, Belgium and Romania.
The number of casualties rose from 22 to 40 as it emerged that 18 had made their own way to hospitals, the BBC reported.
Emergency services rushed to the scene after a large section of the dancefloor gave way, and spent the next few hours evacuating the wounded.
“After the floor collapsed, the people who were inside fell to the basement from the height of approximately one floor,” said the regional government in a statement quoted by AFP news agency.
