President Joe Biden's administration is preparing a $725 million weapons package for Ukraine, two US officials said on Wednesday, as the outgoing US president seeks to bolster the government in Kyiv before leaving office in January, Reuters reports.

According to an official familiar with the plan, the Biden administration plans to provide a variety of anti-tank weapons from US stocks, including land mines, drones, Stinger missiles, and ammunition for High Mobility Artillery Rocket Systems (HIMARS).

The formal notification to Congress of the weapons package could come as soon as Monday, one official said.

The contents and size of the package could change in the coming days ahead of Biden's expected signature.

The US has not exported landmines in decades, and their use is controversial because of the potential harm to civilians.

The landmines that would be sent to Ukraine are "non-persistent" landmines, with a power system that lasts for just a short time, leaving the devices non-lethal. This means that—unlike older landmines—they would not remain in the ground, threatening civilians indefinitely.
