Trump, who turned 79, said: "President Putin called this morning to very nicely wish me a Happy Birthday, but to more importantly, talk about Iran."

Donald Trump has sent Vladimir Putin a stark message after the two leaders spoke for nearly 50 minutes on the phone on Saturday. The US and Russian Presidents discussed Israel 's strikes on Iran, and the possibility of reviving negotiations over Iran’s nuclear programme.

Russian President Vladimir Putin held phone calls with Israeli Prime Minister Benjamin Netanyahu and Iranian President Masoud Pezeshkian on Friday after Israel hit Iran in a series of strikes.

Smirnova, the director of the Narva museum that is housed in the fortress, has defiantly hung from the battlements a large banner of Putin’s face, with the words “war criminal” below it. In January this year a court in Moscow issued an arrest warrant for Smorzhevskikh-Smirnova on the charge of spreading false information.

Russian President Vladimir Putin, in separate telephone conversations on Friday, told Iran's president that Moscow condemned Israel's actions against Tehran and told Israel's prime minister that questions around Iran's nuclear programme could only be solved through diplomacy.

Trump has generally veered away from overtly criticizing Putin while openly berating Ukraine's leader Volodymyr Zelensky, but has repeatedly condemned Russia's lethal airstrikes and floated that the Kremlin could be "tapping us along."

Negotiations between Trump and Putin raise many questions. However, the Kremlin still has no intention of ending the war, says Ukrainian President Volodymyr Zelenskyy in a conversation with journalists on June 13.

Russian leader Vladimir Putin told Iran's president over the phone on Friday that Moscow condemned Israeli actions against Tehran, and in a separate telephone conversation told Israel's prime minister that only diplomacy could resolve issues around Iran's nuclear programme.
