“President Vladimir Putin is rejecting calls to negotiate peace with Kyiv, three sources close to the Kremlin told Reuters, with Ukraine’s recent drone strikes on Russia’s oil refineries and ports strengthening his resolve to keep fighting for now,” Reuters reports.“Two of the sources, speaking on condition of anonymity, said that Putin was instead likely to escalate the conflict, now well into its fifth year. One of them, who meets regularly with the president, described a ‘high probability’ of escalation in the coming months.”
