RUSSIAN despot Vladimir Putin's KH-101 missiles targeted Ukraine's largest hydro plant sparking a huge explosion.
The hydro-electricity base was left in "critical" condition after the 600-mph rocket hit, prompting fears of a catastrophic flood.
It is the second major attack on the Dnipro Hydro-electric Power Plant since March and has crippled its generating capacity.
Any breach of the 200ft dam could cause enormous flooding downstream in the Dnipro river.
Dramatic pictures showed the blaze above the plant, in Zaporizhzhia, as huge explosions hit on Saturday night.
The attack could threaten the Russian-occupied Zaporizhzhia nuclear power plant, the largest in Europe, which requires constant external power to prevent a disaster.

And if Russia continues to attack the dam, floods could hit the Ukrainian cities of Zaporizhzhia, Nikopol and Kherson.
Almost 900,000 people could be impacted by its destruction.
Zaporizhzhia official Ivan Fedorov said: “The Dnipro Hydroelectric Power Station is now in a critical condition.
"We are no longer even talking about generating electricity.

“We will certainly do everything as quickly as possible, and the enemy will answer for all this.”
The dam raises the level of the river some 121 ft between its location in Zaporizhzhia and the city of Dnipro, 80 miles upstream.
The attack came as the Ukrainians were still carrying out repairs from the massive March strike on the plant.
Such strikes by Russia are seen as a direct hit on the civilian population of Ukraine, who are now suffering debilitating electricity outages.
On Friday night Vlad's forces fired over a hundred missiles and drones at Ukraine.
They hit energy facilities in five different regions: Zaporizhzhia, Dnipropetrovsk, Donetsk, Kirovohrad, and Ivano-Frankivsk.
The Kakhovka Dam was breached on 6 June 2023, causing extensive flooding and ecological carnage along the lower Dnipro River.
When Russia struck the plant in March, Putin's forces also used KH-101 missiles.
The long-range rockets cost £10 million and are even capable of obliterating moving targets.
At the time it was thought that at least two of them struck the plant and completely stopped it from generating electricity.
It also put the Zaporizhzhia nuclear plant at risk - less then 200km away.

Petro Kotin, head of Ukraine's Energoatom nuclear power company, said at the time: "Such a situation is extremely dangerous and threatens to lead to an emergency.
"If the last remaining line linking the facility to the national power grid is disconnected, (the plant) will get into another blackout, which is a serious violation of the conditions for the safe operation of the plant.”
