King Bhumibol ascended to the throne 70 years ago, making him the world's longest-reigning living monarch, before his death.
Hundreds of people had for days gathered at Bangkok's Siriraj Hospital where the king was being treated, and as the sun began to set, the crowd began to swell in the thousands.
They were dressed predominantly in pink -- an auspicious color believed to restore health -- and yellow, which is the color of the King, based on the fact he was born on a Monday.
