This is the best summary I could come up with:

Berlin's mayor, its senator for culture and Ukraine's German ambassador have all criticised the opera for allowing the singer to return to its stage.

The city's senator for culture, Joe Chialo, pointedly attended a photo exhibition on Friday entitled Russian War Crimes, across the road from the opera house on Berlin's Unter den Linden.

He was joined by Ukrainian ambassador Oleksii Makeiev, who said on social media that people should not turn a blind eye to Russian war crimes.

She endorsed Mr Putin as president in 2012 and two years later she was photographed holding a pro-Russian proxy flag, having donated money to an opera house in the occupied Ukrainian city of Donetsk.

However, the singer has said she has met Mr Putin "only a handful of times in my entire life" and insists she has received no financial support from the Russian government.

In a recent announcement explaining its decision to cast Ms Netrebko, the opera stressed the importance of distinguishing between her actions before and after the outbreak of the war.
