Ukraine needs “about two billion cubic meters” of additional gas to get through the winter, President Volodymyr Zelensky told G7 nations on Monday.During a video conference he also urged the G7 to send more weapons to Ukraine, including “modern tanks” as well as “rocket artillery and more long-range missiles”. “Unfortunately, Russia still has the advantage in artillery and missiles. This is a fact. These capabilities of the occupying army are the ones to fuel the Kremlin’s arrogance,” Zelensky said.
