Russia set to end energy ceasefire with Ukraine, even as fighting rages

Russia may resume attacks on Ukraine's energy infrastructure after a temporary pause, despite hopes for peace expressed by Donald Trump's envoy. Russian officials have played down prospects of a quick agreement and reiterated tough demands, including recognition of annexed territories and Ukrainian neutrality. Critics question the U.S. negotiating strategy and Trump's reluctance to pressure Russia amid civilian casualties. The ceasefire covering energy infrastructure has been criticized for its vagueness and differing views among parties involved. Ukraine rejects Russia's demands as unacceptable.
