A 46-year-old former Qatari princess has been found dead in her bed at a home in southern Spain, authorities said, AP reported.

Police went to the house after receiving a call from one of Kasia Gallanio's daughters from France, who said her mother was not answering her phone.

Police entered the home with the help of a janitor at the apartment complex and found Gallanio dead in bed with no signs of violence.

Gallanio has U.S. citizenship. An autopsy should determine the cause of death.

According to the French newspaper Le Parisien, Gallanio was married to Abdelaziz bin Khalifa Al Thani, the 73-year-old uncle of the Emir of Qatar.

According to Le Parisien, the children live with their father in Paris.
