US President Joe Biden has approved the transfer of non-persistent anti-personnel land mines to Ukraine, according to the supplied reporting. The move adds another high-profile shift in Washington’s military support for Kyiv as Russian forces continue to press forward on the battlefield.

The decision matters because anti-personnel mines have long been among the most controversial weapons in modern warfare. Biden had previously been reluctant to supply them, citing the threat they pose to civilians. The new package, however, is described as involving a version that is designed not to remain active indefinitely. A US official told Reuters that the mines require a battery to detonate and will stop functioning once the battery runs out after a preset period.

The reporting says Washington expects Ukraine to use the mines on its own territory and that Kyiv has committed not to place them in areas populated by civilians. That distinction is central to the administration’s position, because the civilian-risk argument has historically shaped US policy on land mines and helped keep this category of weapon out of Ukraine’s earlier aid packages.

The approval also comes after Ukraine used US-provided ATACMS missiles against targets inside Russia for the first time, following newly granted permission to use advanced US weapons offensively across the border. The timing suggests a broader willingness in Washington to loosen earlier restrictions as the war evolves and as Russia’s ground campaign continues to deepen pressure on Ukrainian positions.

Al Jazeera’s reporting says the land mines are intended to help stall Russian ground forces that have expanded their advances in recent months. That description points to the immediate tactical logic behind the decision: slowing movement, strengthening defensive lines, and buying time for Ukrainian units already under strain.

The story also lands amid rising tensions between Moscow and Western capitals. Russian officials warned that the ATACMS strikes would trigger a response, while Russian Foreign Minister Sergey Lavrov framed the use of those missiles as a new phase of Western involvement in the conflict. In parallel, the Kremlin said its special hotline with Washington was not in use, underscoring the strain in bilateral communications.

For Ukraine, the new package appears to be part of a wider pattern of incremental but significant changes in US military backing. For Washington, it reflects an attempt to aid Ukraine’s defense while limiting the long-term humanitarian and political consequences that anti-personnel mines have historically carried.

The reporting supplied for this event does not say when the mines will arrive or how many will be delivered. It does, however, make clear that the Biden administration has crossed a line it had previously avoided, and that the decision is tied directly to the changing pace of the war and the expanding range of weapons being used by both sides.

The decision also shows how the US is trying to balance two risks at once: the military need to help Ukraine blunt Russian advances, and the political and humanitarian cost of using weapons that can remain dangerous long after a battle ends. By specifying that the mines are non-persistent and by tying their use to areas without civilians, Washington is trying to narrow the policy exception as tightly as possible. Even so, the move is likely to draw scrutiny from arms-control advocates and will remain controversial because it revives a category of weapon that many governments have tried to move away from.
