Deputy Prime Minister Tan Sri Muhyiddin Yassin has expressed his condolences to Saudi Arabia's royal family and its people over the demise of King Abdullah bin Abdulaziz.

"Al-Fatihah. Condolences to the royal family and people of Saudi Arabia on the passing of King Abdullah," he said in a statement.

The Saudi monarch died early Friday at the age of 90 with reports out of the oil-rich kingdom saying that he was succeeded by Crown Prince Salman bin Abdulaziz.
