Ukrainian President Volodymyr Zelenskyy has called Russia and Iran "brothers in hatred." It came as he visited London to seek support from U.K. Prime Minister Keir Starmer in his country's fight against Russia's invasion. The talks between the two leaders on Tuesday came as the Iran war revives Russia's ailing economy through increased oil revenue, robs U.S.-brokered talks on ending Russia's invasion of Ukraine of momentum, and could soon limit Kyiv's access to vital Western air defense systems that are needed in the Middle East. Starmer said "We can't lose focus on what's going on in Ukraine and the need for our support." NATO Secretary-General Mark Rutte also attended the talks.
