According to another source, the United States and Ukraine are united on the issue of the use of certain weapons by the Armed Forces of Ukraine.

Earlier, British Prime Minister Boris Johnson, as part of a telephone conversation with Ukrainian President Volodymyr Zelensky, spoke about the supply of anti-ship missiles and drones to Kyiv.
