Ukraine will resume attacks on Russian oil refineries, Volodymyr Zelensky said, while accusing the US of withdrawing essential support.
The Ukrainian president said he had limited such attacks for three days on orders from Washington, while Russia continued to strike Ukraine's energy infrastructure.
"The moratorium (on attacks on refineries) no longer exists. We are done with it," Zelensky is quoted as saying, foreign media reports.
Zelensky also accused the US of withholding intelligence on Russian attacks to pressure Kiev to end the attacks completely after reaching a deal to import Russian oil, and said a slowdown in Starlink satellite services used by Ukraine's military was deliberate.
He previously stressed that he would agree to the so-called "energy ceasefire" announced by US President Donald Trump on Sunday if Moscow also respected it.
But Zelensky accused Russia of ignoring the proposed deal within hours of its announcement, with attacks that left hundreds of thousands of Ukrainians without power.
The Kremlin never said it agreed to the deal.
Zelensky admitted he felt betrayed by the US when asked by Piers Morgan on Wednesday evening, as Washington appeared to withdraw key elements of his support.
The Ukrainian leader told the FT that Ukrainian officials had been told by their US counterparts that “if you don’t stop [the attacks], we will block the intelligence”.
