Kremlin says Biden 'fuelling' tensions by permitting missile strikes

The Kremlin said on Monday that US President Joe Biden's outgoing administration will further inflame tensions by allowing Ukraine to use long-range missiles for strikes inside Russia.

Kremlin spokesman Dmitry Peskov said he had seen media reports that Biden cleared strikes, adding: "It's obvious that the outgoing administration in Washington intends to take steps in order to continue fuelling the fire and provoking further escalation of tensions".

A US official, speaking on condition of anonymity, confirmed to AFP reports from The New York Times and The Washington Post that the major policy shift -- long demanded by Ukraine -- was in response to North Korea deploying troops to help Moscow's war effort.

Ukrainian President Volodymyr Zelensky has long pushed for authorisation from Washington to use the powerful Army Tactical Missile System, known by its initials ATACMS, to hit targets inside Russia.

"If such a decision was really formulated and announced to the Kyiv regime, then of course it's a qualitatively new spiral of tensions and a qualitatively new situation from the point of view of the US's engagement in the conflict," Peskov told journalists.

He said President Vladimir Putin had expressed Russia's position clearly in September when the leader said that such a move would put NATO "at war" with Russia.

In such a case, "we will take the appropriate decisions based on the threats that we will face," Putin said in September.
