A British woman and her eight-year-old daughter have been injured in an explosion at a hotel on the Spanish holiday island of Tenerife, sources said.
The woman was taken to hospital with severe burns to her face and scalp following the blast in the Bahia Principe hotel in Playa Paraiso on the south-west coast of the island on Friday afternoon.
Her daughter suffered less serious neck burns and both are believed to be receiving ongoing treatment in separate hospitals.
Local authorities claimed that a British man had also suffered minor abrasions in the blast, although this was denied by a hotel spokesman.
A Foreign Office spokeswoman said: "We are aware of an incident involving two British nationals and are providing consular assistance.
"We are currently checking, but based on what we know so far there was no British man injured in the explosion."
A spokesman for the Bahia Principe claimed that the British woman's husband and a second daughter had avoided injury but were "obviously in shock" at what had happened.
"This was an accident and we still are not sure what went wrong - we are awaiting the investigation of the judicial police," he said.
"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."
Two more women - a 38-year-old Belgian woman and a 34-year-old Spaniard - were also treated for minor burns in hospital.
A spokesman for the Canary Islands government said: "At 4.09pm on Friday emergency services were called to an explosion in a machine in a poolside bar at a hotel in Playa Paraiso, 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."
The Bahia Principe describes itself as hotel with "marvellous facilities, lush green gardens and infinity pool", offering an "unforgettable vacation" and "beautiful views of the sea and of La Gomera island".
The Costa Adeje resort is a popular destination for British tourists, with nearby sand beaches such as Playa de Las Americas and Los Cristianos particularly well known.
The area boasts a lively night-life in addition to golf clubs, zoos and other leisure activities such as go-karting, fishing, sailing and dolphin and whale watching.
Enjoying year-round good weather, the Canary Islands receive thousands of British holidaymakers during the cold winter months.
Temperatures tend to range from around 24C in summer to 17C in winter.
