(AP) — Workers and volunteers piled sandbags outside buildings in central Bangkok and erected barriers in its subway to ward off possible weekend flooding as high water that devastated parts of central Thailand flowed toward the low-lying metropolis.
While the government sought to reassure Bangkok’s 9 million people that the capital would be spared, it also sent sometimes confusing messages that raised anxieties and sent residents on shopping sprees to stockpile food, medicine and other essentials.
The worst floods in a half-century have submerged entire towns across Thailand’s central plains, devastating rice crops and halting hundreds of factories. Some 8.2 million people in 61 of Thailand’s 77 provinces have been affected by the flooding, which has killed 283 people since July.
