Washington’s stance about unacceptability of using US weapons for strikes on the Russian territory remains unchanged, White House National Security Council Strategic Communications Coordinator John Kirby said, Paralel.Az reports citing TASS.

"There's no change in our policy. We do not encourage nor do we enable attacks using US weapons on Russian soil," he said, answering a reporter’s question at a briefing.

"I don't have any changes to speak to," he continued, adding that the format of US military support to Ukraine "has evolved appropriately as the battlefield conditions have evolved."
