Thailand is mourning King Bhumibol Adulyadej. King Bhumibol died Thursday in Bangkok. He was 88 years old. In recent years, the king suffered from a series of age-related health problems that mostly kept him in a Bangkok hospital. Last weekend, Thai officials announced that his health had worsened and his condition was “not stable.” Officials said on Thursday his health never improved and that he died peacefully. A large crowd had gathered outside the hospital where the king was being treated. Many in the crowd broke down with emotion after hearing of his death. Some held photographs of the king and wore yellow or pink clothing in his honor. King Bhumibol came to power 70 years ago. He was the world’s longest serving monarch. He was born in 1927 in the American community of Cambridge, Massachusetts, where his father was studying medicine.
