MUNICH (AP) — The first keg has been tapped and the beer is flowing as the 185th Oktoberfest gets underway in Munich.

Mayor Dieter Reiter inserted the tap in the first keg on Saturday with two blows of a hammer and the cry of "O'zapft is" — "it's tapped." As tradition demands, he handed the first mug to Bavarian governor Markus Soeder, who declared that "the Oktoberfest is perhaps Bavaria's biggest and best visiting card in the world."

Around 6 million visitors are expected at the festival grounds in Munich before the Oktoberfest ends on Oct. 7. As in previous years, backpacks and large bags are banned for security reasons.

Beer prices are up again, with a liter (2-pint) mug costing up to 11.50 euros ($13.50) — a 55-cent increase over last year.
