A British woman is being questioned by Spanish police after two of her children were found dead in a holiday resort in Spain.
Police said the children, a boy and a girl both under the age of six, were discovered in a hotel room in the coastal town of Lloret de Mar.
The British Embassy in Madrid said an inquiry had been launched into the deaths.
A Foreign Office spokeswoman said it was investigating the reports.
A spokesman said: "We are in contact with the Spanish police but because the children are minors we cannot say much.
"We believe the mother has been arrested. There is an ongoing investigation."
‘Popular with British’
Police were called to the four-star Hotel Miramar, located on the Costa Brava coast 47 miles (75km) north of Barcelona, at about 2pm local time.
A Girona police spokesman said: "At around 3.53pm, the mossos de la comissaria de Blanes (local police) received a note from the local police of Lloret de Mar that the bodies of two minors had been found at a hotel.
"When the officers arrived at the scene they found two children inside a room at a hotel.
"Girona Police are investigating the death of the two children. The police have detained the mother of the minors to find out what happened."
Spanish newspaper El Mundo reported that the children’s mother phoned police, who were unable to revive them.
Embassy staff said they were trying to establish whether the family was on holiday in Spain or living in the country.
Lloret de Mar is a popular destination for British holidaymakers.
A spokesman for travel association Abta said: "It’s very popular with the British. It’s a very traditional Spanish resort, similar to Benidorm and Torremolinos."
