BERLIN — Bavarian officials on Monday canceled Oktoberfest festivities for a second year in a row due to concerns over the spread of COVID-19, saying there are too many risks in hosting the celebrations — which bring in visitors from around the world — during a global pandemic. Bavarian Governor Markus Soeder said it was with “heavy hearts” that they decided to call off the festival for which the state is known globally, but that with coronavirus numbers still stubbornly high and German hospitals already struggling, it had to be done.
