Belgium's Queen Fabiola undergoes surgery
The 80 years old was operated on her thyroid gland.
"Queen Fabiola is at the Liege University Hospital Centre where she underwent a planned benign operation," spokesman Pierre-Emmanuel De Bauw told AFP.
He did not give details about her condition.
Fabiola, who is 80 years old, was Belgium's queen consort between 1960 and 1993.
French-speaking private RTL-TVI television said Fabiola was operated on her thyroid gland on Thursday.
The thyroid regulates the body's metabolism.
