Ukrainian President Volodymyr Zelensky offered to go beyond the agreement U.S. President Donald Trump said he had secured from Russian President Vladimir Putin not to strike Ukraine's energy grid for a week during the brutal winter weather, suggesting a broader truce. Meanwhile, Ukraine has repeatedly struck Russia's lucrative oil and gas sector to deprive it of revenue that funds the war. Zelensky, speaking to journalists on Friday morning, said there had been no direct contact between Russia and Ukraine on the issue, which he described as an "opportunity, not an agreement." "If Russia does not strike our energy sector—generation or any part of it—we will not strike their energy sector. I think this is the answer the mediator of the negotiations, namely the United States of America, was expecting," Zelensky said.
