The US has not found any evidence that weapons it has provided to Ukraine have been found outside of Ukraine, according to the assistant secretary of defense for international security affairs, CNN reports.
"Instead, we see Ukraine's frontline units effectively employing security assistance every day on the battlefield," Celeste Wallander told the House Appropriations Subcommittee on Defense.
The US has adapted its accountability practices for combat environments to avoid the risk of illicit diversion, she added.
Another top Pentagon official, Lt. General Douglas Sims, stated that there are no reports that weapons have gone missing from Ukraine, and it would not be in the interest of the Ukrainians to get rid of them.
