U.S. President Donald Trump announced on social media on Sunday that Russia and Ukraine had reached an "energy ceasefire" agreement, effective "immediately." Ukrainian President Volodymyr Zelenskyy responded that Ukraine is willing to support an energy ceasefire if Russia also agrees, which could "be an important step towards ending the war." However, Russia has not yet confirmed the agreement, and Zelenskyy also stated that Russia "immediately" attacked a Ukrainian power plant in Kharkiv after Trump's post.
