Construction workers uncovered an unexpected threat near London’s Wembley Stadium, just ahead of this weekend’s soccer playoffs: an unexploded World War II bomb that authorities say continues to pose a threat. They are working to defuse the explosive, which has a 650-foot blast radius. Nearby businesses, including studios recording the Britain’s Got Talent TV show, have been evacuated, and officials have built a blast wall around the device in case something goes wrong. They say they hope to have it taken care of ahead of the weekend’s games.
