Russia's top diplomat on Tuesday blamed the US for the breach in the Kakhovka dam.
He said Ukraine used US-supplied HIMARS to attack the dam, citing a media report from December.
At a UN security council meeting, Nebenzya said earlier media reports recorded Ukrainian forces attacking the dam with HIMARS in December.
The Post reported that Kovalchuk conducted a test strike with a HIMARS launcher targeting a floodgate at the Kakhovka dam.
On Kyiv's part, Ukrainian UN ambassador Sergiy Kyslytsya said it was "physically impossible" to destroy the Kakhovka dam from the outside.
