The drones at SPIEF and Zelensky’s letter to Putin are part of Ukraine’s new “military-diplomatic campaign.” Here's what Ukrainskaya Pravda sources from Zelensky's team say about her

On June 3, the opening day of the St. Petersburg International Economic Forum (SPIEF), the city was attacked by Ukrainian drones. On June 4, Vladimir Zelensky published an open letter to Vladimir Putin calling on him to meet and end the war. However, the tone of the letter was more attacking than conciliatory. Putin refused to meet.
