Russia has warned that escalation will occur if the United States supplies Ukraine with Tomahawk missiles.
This update came from the Kremlin just one day after U.S. Vice President JD Vance said on Sunday that Washington was weighing up a request from Ukraine for the missiles.
A final decision is still to be made by President Donald Trump, who has been showing increasing frustration with Russia over the ongoing refusal of a ceasefire.
Tomahawk missiles have a range of 2,500 kilometres, which, if fired from Ukraine, would have the ability to strike Moscow and most of European Russia.
"The question... is this: who can launch these missiles...? Can only Ukrainians launch them, or do American soldiers have to do that?" Kremlin spokesman Dmitry Peskov told reporters when asked about Vance's remarks on Monday, saying that "a very in-depth analysis" was needed.
Andrei Kartapolov, head of the Russian parliament's defence committee, also said that U.S. military specialists who helped Ukraine to launch Tomahawks against Russia would become targets.
"And no one will protect them. Not Trump, not Kellogg, nor anyone else," he said.
Ukraine's President Volodymyr Zelenskyy has asked Washington to sell Tomahawks to European nations that would then send them to Ukraine, but logistics remain uncertain.
In an interview last week, the Ukrainian leader said that he had President Trump's explicit backing to hit major Russian targets, including energy infrastructure and arms factories.
“They [Russian officials] have to know where the bomb shelters are,” he said.
“They need it. If they will not stop the war, they will need it in any case.”
