The UK foreign office said it was "urgently seeking updates" on the flooding, as reports emerge that a British couple has died.
Ten people, including two Britons, have been killed in flash flooding on the Spanish island of Mallorca, authorities said on Wednesday.
A child is still missing following the heavy rains on Tuesday in the municipality of Sant Llorenc, the local emergency services said.
A senior official from the Sant Llorenc mayor’s office, Antonia Bauza, told radio station Cadena Ser that two of the victims were British.
The UK Foreign Office earlier responded to questions about the reported fatalities with a statement to Euronews saying: “We are in contact with the Spanish authorities responding to flooding in Majorca, and urgently seeking updates from them.”
The town of Sant Llorenc is around 60 kilometres east of Palma — the capital of the Mediterranean island. It was deluged by torrential rain on Tuesday evening.
Dramatic video footage on social media shows raging torrents of water gushing through the streets of the town, with reports that more than 20 centimetres of rain fell in just four hours.
Prime Minister Pedro Sanchez offered a message of "solidarity and support" to "all those affected by these tragic floods."
Lawmakers held a minute’s silence before the weekly prime minister’s question time in parliament on Wednesday morning.
