Update(1220ET): Fresh off a Wednesday morning phone call with President Trump, Zelensky has said that he backs the US proposal to halt all strikes on energy facilities in the context of the Ukraine war, according to Bloomberg. Still, he has at the same time vowed to 'win this war'.

Just hours prior, overnight, Ukrainian drones had targeted a Russian oil facility in Krasnodar Region, resulting in damage and a large fire at a oil tank. The one-hour phone call was described as "very good" by Trump on Truth Social.

"Much of the discussion was based on the call made yesterday with President Putin in order to align both Russia and Ukraine in terms of their requests and needs," the president wrote.

"We are very much on track, and I will ask Secretary of State Marco Rubio, and National Security Advisor Michael Waltz, to give an accurate description of the points discussed."

If the tit-for-tat strikes on energy facilities actually halt for the 30-day period, this could indeed jump-start other major agreements, a first in the war.

During Tuesday's Trump-Putin phone call, which lasted some 90-minutes, the White House said that President Putin committed to a halt of attacks on Ukraine's energy infrastructure for a period of 30-days. The Kremlin readout also appeared to acknowledge and agree to this.

Less than 24 hours later, Russia has accused Ukraine of already breaking the Trump agreement. Russia's defense ministry on Wednesday said Ukraine attack an oil transfer facility in Russia's Krasnodar Region that services an international pipeline operation partially owned by American investors.
