Russia said it was responding to comments by Vadym Skibitsky, Ukraine's deputy head of military intelligence, about the way Kyiv used U.S.-supplied long-range HIMARs rocket launch systems based on what he called excellent satellite imagery and real-time information, Reuters reported.
Skibitsky told Britain's Telegraph newspaper there was consultation between U.S. and Ukrainian intelligence officials before strikes and that Washington had an effective veto on intended targets, though he said U.S. officials were not providing direct targeting information.
Russia's Defence Ministry said the interview showed that Washington was directly involved despite repeated assertions that it was limiting its role in the conflict to arms supplies because it did not want a direct confrontation with Moscow.
"It is the Biden administration that is directly responsible for all Kyiv-approved rocket attacks on residential areas and civilian infrastructure in populated areas of Donbas and other regions, which have resulted in mass deaths of civilians," the Defence Ministry said.
Supplies of sophisticated long-range weapons systems from Western nations to Ukraine are seen as vital if Kyiv's forces are to turn the tide of the war.
