The Royal Palace said Bhumibol, the world’s longest-reigning monarch since his 1946 coronation, died at Siriraj Hospital in Bangkok. Officials did not give a cause.Officials said he “passed away peacefully” at 3.52 p.m. local time. The government declared a year of mourning.


Although he had no formal political role, Bhumibol was a unifying figure through the nation and widely respected by a majority of Thais. He had been hospitalized for many years, making only limited public appearances.


“It’s a great loss to Thai people,” Prime Minister Prayuth Chan-Ocha said.
