Biden approves anti-personnel mines for Ukraine in policy shift before leaving office

President Joe Biden has approved sending anti-personnel landmines to Ukraine, marking a significant policy shift as he seeks to support President Volodymyr Zelensky before leaving office. Ukraine plans to use these mines only on its territory and away from civilian areas. This decision follows Biden's recent approval for Ukraine to use long-range ATACMS missiles, allowing strikes deeper into Russian territory. The U.S. embassy in Kyiv has closed due to intelligence about a potential air attack. Russia has reacted strongly, claiming these actions signal an escalation of the conflict. President Vladimir Putin has adjusted Russia's nuclear doctrine, stating that conventional attacks supported by nuclear powers could justify a nuclear response.
