Thailand's Royal Palace says King Bhumibol, the world's longest-reigning monarch, has died at age 88.

The palace said the king passed away peacefully on Thursday at Bangkok's Siriraj Hospital.

"Even though the board of doctors has closely monitored and treated him to the best of its abilities, the king's condition never improved but deteriorated until Thursday," it said in a statement issued about three hours later.

TV stations announcers wore black clothes as they discussed his passing. The brief announcement mentioned his 70-year-reign and noted that he passed away peacefully.
