Two British tourists have drowned in the sea off Tenerife after reportedly trying to rescue their children.
The female victims, 42-year-old Uma Ramalingam and her relative Barathi Ravikumar, 39, went to help the youngsters after they were swept away by a wave.
But the women - both doctors - got into difficulties themselves near the resort of Playa Paraiso in the southwest of the island on April 6th.
The youngsters, aged 10 and 14, were rescued by tourists and hotel workers while an emergency services helicopter pulled a third woman, 38, out of the water.
She and the two children survived but the two other women each suffered a cardiac arrest and attempts to revive them were unsuccessful.
A spokeswoman for Canary Islands emergency services said: "At just after 6pm yesterday afternoon we received several calls alerting us to two people who were in difficulties in the sea.
"Witnesses rescued two women and two children from the sea. An emergency helicopter located a fifth person in the sea, a woman, and one of the respondents dangled out of the craft and pulled her out.
"Staff from the Canaries health service, a doctor from a nearby health centre and another doctor who was at the scene found that two women were in cardiac arrest and tried to give them advanced CPR without success.
"They later certified the death of both women. They also helped stabilise the other people, taking a woman and a child to hospital."
The 10-year-old child was reportedly taken to hospital with hypothermia while the 14-year-old was treated for minor bruises at the scene.
The third woman was in cardiac arrest when she was rescued but survived after receiving CPR.
A Guardia Civil spokeswoman confirmed the two women who died were British and relatives of the children, but said it had not been ascertained how they were related. An investigation is now under way.
Dr Ramalingam was a consultant obstetrician at the Royal Oldham Hospital.
Mr Olubusola Amu, from the Pennine Acute Hospitals NHS Trust, said: "We are greatly saddened to hear the death of Uma who had been working for the Trust for about six years.
"She was a fantastic doctor who brought a lot of hope to the high risk women attending the Women and Children's Unit at The Royal Oldham Hospital.
"This is a terrible shock to everyone who knew Uma. Our thoughts are with her family at this sad time. She will be sorely missed."
Dr Ravikumar was a partner at a health surgery in Bracebridge Heath, Lincoln and has been described as "a hard-working and dedicated GP" who "always worked in the best interests of patients".
A statement on her surgery's website said: "During her short time with the practice she was passionate about making a difference to healthcare in Lincolnshire and specialised in working with Looked After Children.
"Dr Ravikumar will be sorely missed and leaves behind a husband and two children."
In a joint statement, Dr Mohammed Zubair Qureshi, Dr Ashfaq Qureshi and Dr Rama Srinivasan, partners at the Heath Practice, added: "It is with great sadness and shock that our practice has learned of the tragic death of Dr Barathi Ravikumar, a hardworking and dedicated GP.
