Their Majesties the King and Queen have expressed shock and profound sadness at the deadly earthquake that hit Cianjur in West Java, according to a statement released by the Royal Household Bureau.
"We were especially shaken not only by the rare severity of the quake but also because it was so sudden, coming so soon after our most cordial meeting with Your Excellency and Madame Widodo during the Apec summit in Bangkok," His Majesty said a letter to Indonesian President Joko Widodo.
A great many lives have been lost, with countless numbers either injured or missing and, not least, the widespread destruction to homes and infrastructure, the letter said.
His Majesty, on behalf of the people of Thailand, extended his heartfelt sympathy and condolences to the president and the people of Indonesia, who have been inflicted with grief and bereavement.
