It has been less than 24 hours since an expanded Ukrainian 'partial ceasefire' was announced to include not just a 30-day halt in attacking energy infrastructure, but a pause in attacks in the Black Sea, and already there are accusations that the deal has been broken once again.

Russia has said the naval ceasefire would only come into force after Washington lifts sanctions against its food and fertilizer trade. The energy and Black Sea ceasefires were announced Tuesday, having been agreed to in separate meetings between both waring countries and the US in Saudi-hosted talks.

The Russian Defense Ministry has said that overnight there were several new attacks targeting Russia's energy infrastructure, including UAVs sent against the Glebovskoye underground gas storage facility in Crimea.
