Adding to the list of setbacks and stumbles for the Rio Olympics, the athletes’ village, home to thousands of athletes during the Summer Games, has been called unfit for occupancy.Sunday was supposed to be move-in day for many athletes, but the leader of the Australian Olympic delegation said its athletes would not be checking in because of problems with the gas, electricity and plumbing. Among the issues with housing units at the village were blocked toilets, leaking pipes and exposed wiring. There was also bad lighting in many stairwells and dirty floors in need of a massive clean. The opening ceremony for the Rio Games is scheduled for Aug. 5.
