This is reported by the Washington Post, citing American and Ukrainian officials.
According to the publication's sources, the Biden administration is aiming to slow down Russia's advance, and thus considers the transfer of mines a beneficial step in this regard.
This type of anti-personnel mine is "unstable," says one unnamed official. This means that the mines self-destruct or lose battery charge, becoming inactive. This reduces the danger to the civilian population.
In the U.S., it is noted that Ukrainians have committed not to deploy such mines in densely populated areas, and their use will be restricted to the territory of Ukraine—primarily the east.
It is important to note that the use of anti-personnel mines is prohibited by the Ottawa Convention, which Ukraine has signed. However, neither the U.S. nor Russia has signed this document.
One Ukrainian official, who spoke with journalists, welcomed the provision of anti-personnel mines to Ukraine, despite the risks they pose. According to him, "Russia is using them anyway."
