The tributes
Tributes have been flowing in from across the world.
US President Barack Obama called the late king a "tireless champion of his country's development".
"I had the honour of calling on his majesty the king during my visit to Thailand in 2012, and recall his grace and warmth, as well as his deep affection and compassion for the Thai people," he said.
UN Secretary General Ban Ki-Moon said in a statement that he hoped Thailand would honour King Bhumibol's legacy of commitment to universal values and respect for human rights.
Asian leaders were quick to express their condolences. Indian Prime Minister Narendra Modi described the late king as "one of the tallest leaders of our times".
