Two British people were among four injured after an explosion in a hotel pool bar on the island of Tenerife.
A woman suffered serious burns to her face and scalp in the blast in Adeje, on the south-west coast of the island, on Friday evening.
Her eight-year-old British daughter was also injured and treated for less severe neck burns.
Two other women – a Belgian national aged 38 and a 34-year-old Spaniard – suffered minor burns and were taken to hospital.
A staff member at the Bahia Principe Costa Adeje hotel confirmed there was an explosion on Friday.
A spokesman said the British woman’s husband and a second daughter had avoided injury, but were “obviously in shock”.
He said: “This was an accident and we still are not sure what went wrong – we are awaiting the investigation of the judicial police.”
“The explosion took place in a metal buffet container by the pool which uses a flammable gel to keep food warm.”
“The swimming pool is now open again and the hotel is back to normal. We would like to wish those who were injured a speedy recovery.”
Local authorities had claimed a British man also suffered minor abrasions in the blast, but this was denied by the spokesman.
Earlier, Ross Browning, editor of Canarian Weekly, said: “It’s awful what’s happened and with so many people around, in many ways it’s probably a miracle that only five people have been injured.”
“The woman has been transferred to La Candelaria in the north of the island with what is being described locally as severe burns to the face, neck and scalp.”
A statement from local government in Adeje said: “At 4.09pm on Friday emergency services were called to an explosion in a machine in a poolside bar at a hotel in the town of Adeje, with several people suffering from burn injuries.”
“Emergency resources were immediately mobilised. Fire crews attended to inspect the zone, but their intervention was not necessary.”
A Foreign Office (FCO) spokesperson said: “We are aware of an incident involving two British nationals and are providing consular assistance.”
