One of the princes of the Saudi Arabia ruling family, Al-Waleed bin Khalid Al-Saud, died on Saturday after spending almost 20 years in a coma following a car accident, according to the royal office.

The member of the royal family, who spent such a long time in a coma, was called the "sleeping prince" in Saudi Arabia.

There were periodic rumours that he was getting better, which were not confirmed.

"A prayer service for the prince's funeral will be held on Sunday at the Imam Turki bin Abdullah Grand Mosque in Riyadh," the office said in a statement, cited by the state-run news agency SPA.

The information about the death of the 35-year-old prince was confirmed on X by his father, Khalid bin Talal, who for 20 years refused to turn off life support and believed that his son would come out of the coma.

He regularly posted numerous photos on social networks after visiting his son in the hospital, including on various holidays.

According to news reports, his father quoted a verse from the Quran and wrote: “With hearts believing in Allah’s will and decree, and with deep sorrow and sadness, we mourn our beloved son: Prince Al-Waleed bin Khaled bin Talal bin Abdulaziz Al Saud, may Allah have mercy on him, who passed away today.”

Al-Waleed suffered a brain haemorrhage and internal bleeding in a horrific accident in 2005, when he was just 15 years old.
