The opening night of a revival of Richard Wagner’s “Tannhäuser” at the Metropolitan Opera in New York was interrupted Thursday night by climate protesters shouting “No Opera” from the balconies on both sides of the opera house.

Protesters with the group Extinction Rebellion NYC unfurled banners that read “No Opera On A Dead Planet,” according to Peter Gelb, the general manager at the Met. Met officials were then forced to bring down the curtain at around 9:30 p.m., halfway through the second act.

About eight minutes passed before security officials ushered out the protesters perched on the balconies, Mr. Gelb said.

The crowd jeered the demonstrators and burst into applause when the curtains again opened, but the elation was short-lived.
