President Trump raised eyebrows when on Monday he declared that Russia and Ukraine had agreed to stop attacking each other's oil and energy infrastructure, amid global crude and diesel supply problems related mostly to the Hormuz Strait crisis.

But then within days later it became clear that the default reality on the ground has persisted, as energy sites continue to get pummeled. And it's not only refineries and ports which have continued getting hit, but as of Thursday morning a Russian nuclear plant was apparently targeted in a Ukrainian drone attack.

A drone hit the cooling tower of a reactor unit at Russia's Kursk Nuclear Power Plant, the International Atomic Energy Agency has announced Friday.

The unit was operating at the time, but its operating mode was unchanged and no fire broke out.
