Prince Ehsanullah, son of former King Amanulllah Khan, passed away in Swiss, the Presidential Palace said in a statement on Saturday.
The statement said President Ashraf Ghani and the First Lady Rula Ghani talked with Princess Hindia, the daughter of King Amanullah Khan, in a phone call on Saturday and expressed their condolences to the princess over the death of his brother.
Amanullah Khan was the first Afghan ruler who gave liberty to women, allowed them to attend school and attempted to modernize Afghanistan before a popular uprising led him to flee to British-controlled India in 1929.
