Police examine BDU-33 practice bombs unearthed at a construction site in Bangkok, Thailand, March 19, 2018. A cache of World War II era practice bombs, which were 45 centimeters long and weighed about 11 kilograms each, was uncovered by an excavator. They were not functional and were at least 45 years old. They had not belonged to the Thai military. It was likely they had been left there by US forces after World War II. (Photo/IC)
