MOSCOW -- Russia and the United States have agreed on a category list of energy facilities spared from being targeted during a 30-day energy ceasefire in the Russia-Ukraine conflict, according to a Kremlin statement Tuesday.

The list includes oil refineries, oil and gas pipelines and storage facilities, electricity generation and transmission infrastructure, nuclear power plants, and hydroelectric dam facilities.

The Kremlin added that the 30-day ceasefire on energy facilities is in effect starting from March 18 and may be extended by mutual agreement or cease to be in effect if violated by one of the parties.

In an earlier statement, the Kremlin noted that Russia and the United States agreed to form measures to implement the 30-day ceasefire agreement.

Russia and Ukraine held separate talks with the United States in Riyadh, capital of Saudi Arabia, on March 23-25.

Ukrainian Defense Minister Rustem Umerov said earlier in the day after the talks with the US delegation that "all parties" agreed to develop measures implementing the energy facility ceasefire.
