The monarch of Morocco, King Mohammed VI has reportedly suffered a viral lung infection.
His doctors have now asked him to take a long rest to recover.
The illness forced him to miss a remembrance ceremony in Paris for France’s late president Jacques Chirac.
An official statement from the palace said on Sunday the 56-year-old monarch, was unable to the commemoration event for Chirac, who died last week aged 86.
Last year King Mohammed VI underwent heart surgery. He has been in power since 1999 when he took over from his father.
He is heading the Muslim world’s longest-serving dynasty succeeding his father Hassan II.
Mohammed VI is worth some $5.7 billion, according to Forbes. His “wealth comes mostly from investments.”
King Mohammed VI “controls Moroccan investment holding company Societe Nationale d’Investissement,” whose assets are estimated to be worth more than $9 billion.
The Moroccan King also has investments in the financial, mining, telecommunications, and distribution sectors.
Mohammed represents the supreme authority in Morocco.
