People pray for the health of Thailand's revered King Bhumibol Adulyadej at the Siriraj hospital in Bangkok October 5, 2014. King Bhumibol Adulyadej, the world's longest-reigning monarch, was readmitted to a Bangkok hospital late on Friday after leaving it last month, the palace said in an announcement on Saturday. The 86-year-old king has been admitted for a high fever and the diagnosis suggested blood infection, so doctors had asked him to stay at Siriraj hospital for special treatment, the Bureau of the Royal Household said in a statement.
