A Belgian prince has contracted coronavirus after attending a party during lockdown in Spain, the country's royal palace says.
Prince Joachim, 28, travelled from Belgium to Spain for an internship on May 26, the palace said.
Two days later, he went to a party in the southern city of Córdoba before testing positive for Covid-19, reports BBC.
Spanish reports suggest the prince, a nephew of Belgium's King Philippe, was among 27 people at the party.
Under Córdoba's lockdown rules, a party of this size would be a breach of regulations, as gatherings of no more than 15 people are currently permitted.
Spanish police have launched an investigation into the party. Those found to have flouted lockdown rules could be fined up to €10,000 (£9,000; $11,100).
Everyone who attended the party is said to be in quarantine. Prince Joachim, the youngest son of Princess Astrid and 10th in line to the Belgian throne, is said to have mild coronavirus symptoms.
Rafaela Valenzuela, a representative of the Spanish government in Córdoba, condemned the party, calling those who attended "irresponsible".
"I feel surprised and angry. An incident of this type stands out at a moment of national mourning for so many dead," she said.
