MOSCOW, June 7. /TASS/. The US authorities must give a concrete answer as to whether or not they know how American weapons are being used on the territory of Ukraine, Russian Foreign Ministry Spokeswoman Maria Zakharova told a briefing in comments on the attack on the Kakhovka Hydroelectric Power Plant.

Against the backdrop of the recent attack on the Kakhovka HPP, she pointed to a statement made last December by Ukrainian General Andrey Kovalchuk in an interview with The Washington Post, in which he said that the Ukrainian army had already conducted a test strike from a US HIMARS system on one of the dam's gates to punch it and see how high the water level of the Dnieper River rises.

"Now, the question for [White House National Security Council Coordinator for Strategic Communications John] Kirby, [White House Press Secretary] Karin Jean-Pierre, all the people who are in charge of communications at the White House. <...> Were you aware of how American weapons, the weapons that are being supplied to Ukraine, are used?" she asked.

"That trial tests of a terrorist attack against civilian infrastructure in third countries are being made? These are the questions that we directly pose in the public space before the White House; you must answer them," she said, adding that the attack on the Kakhovka HPP "is certainly an act of terrorism."

On Tuesday night, Ukrainian forces delivered a strike on the Kakhovka hydropower plant, presumably from an Olkha multiple launch rocket system (MLRS). The shelling destroyed the hydraulic sluice valves at the HPP’s dam, triggering an uncontrolled discharge of water. In Novaya Kakhovka, the water level exceeded 12 meters at one point, but is now receding. There are currently 15 population centers in the flood zone; residents of nearby towns and villages are being evacuated. The collapse of the hydro plant's dam has caused serious environmental damage. Farmlands along the Dnieper River have been washed away, and there is a risk that the North Crimean Canal will become shallow.
