The US statement on Kiev's use of HIMARS reveals their involvement in the conflict, Kremlin spokesperson Dmitri Peskov told to journalists on Wednesday.

"Such statements both directly and indirectly are new evidence of the United States' direct involvement in this conflict, which creates an extremely dangerous situation," Peskov stressed.

Earlier on Tuesday, US Deputy Assistant Secretary of Defense for Russian, Ukrainian and Eurasian Affairs Laura Cooper said that the HIMARS provided by Washington to Kiev allow the AFU to hit most targets, including in Crimea.

"It's our assessment that with the existing GIMLRS [Guided Multiple Launch Rocket System] capability that they have on the HIMARS and that we're providing more of, with this package, that they can reach the vast majority of targets on the battlefield, including Crimea," Cooper said.

On the same day, US President Joe Biden stated during a phone call with Ukrainian President Volodymyr Zelensky that a new $625 million military aid package had been allocated to Kiev.

According to the White House, the package includes 'additional weapons and equipment, including HIMARS, artillery systems and ammunition, and armored vehicles'.

Moscow launched the military offensive on Ukraine in late February after recognising the LPR and DPR.

Kiev denounced the Russian offensive into its territory, and Zelensky imposed martial law throughout the country, announcing a general mobilisation.
