German Chancellor Friedrich Merz on Sunday called on Iran to "immediately stop" its "indiscriminate attacks", while predicting that the country's rule by clerics was coming to an end with the death of supreme leader Ayatollah Ali Khamenei.
Germany shares Iranians' "relief" to see the "mullah regime come to an end", Merz said at a press conference in Berlin.
He cautioned however that the killing of Khamenei in strikes by the US and Israeli on Tehran had set Iran on a path to an "uncertain future".
Merz confirmed he would be travelling to Washington on Tuesday on a scheduled trip and would discuss Middle East developments with US President Donald Trump.
"Ultimately, we don't know if the plan will succeed," he said of the US-Israeli strikes in which Germany, like Britain and France, did not participate.
He said that Germany would not tolerate any "antisemitic or anti-American" attack on its soil.
