Abdullah bin Abdulaziz al Saud, who became the King of Saudi Arabia in 2005, died early on Friday morning following lung infection and pneumonia. He was 90.
Following the death of the King, mourners gathered in Mecca to pay their last respects.
Latest reports suggest that his half brother Prince Salman bin Abdulaziz has been appointed as the new king of the country.
Special services will be held on Friday afternoon at the Imam Turki Bin Abdullah Grand Mosque in Riyadh and many leaders from around the world are likely to attend the service to pay tribute to the late leader.
The late King had earlier met various world leaders, including Barack Obama, George W Bush, Queen Elizabeth II, Pope Benedict XVI, German Chancellor Angela Merkel, U.N. Secretary General Ban Ki-moon and France's former President Nicolas Sarkozy, among others.
