The Kremlin has said the possible use of long-range US missiles on targets in Russia would ultimately lead to a “new round of tension” amid media reports that outgoing President Joe Biden allowed lifting restrictions on their use by Ukraine. On Sunday, many media outlets citing anonymous officials, including The New York Times, reported that Biden has authorised Ukraine’s use of ATACMS missiles for strikes inside Russia, marking a major change in US policy ahead of the inauguration of president-elect Donald J Trump in January 2025.
