The warning comes in the wake of baseless Russian allegations that Ukraine
intends to use a "dirty bomb" on its own soil, which U.S. officials believe
might be used as justification for Moscow to escalate the conflict.
Volodymyr Zelenskyy, the president of Ukraine, has also charged that Russia
intends to blow up a sizable dam close to Kherson and blame Ukrainians for
it.
The United States has sent more than $17 billion in military aid to Ukraine
since Russia started its conflict there eight months ago, including
everything from armoured vehicles, howitzers, and shoulder-fired rockets to
cutting-edge air defence systems. Recent weeks have seen an increase in
calls for stricter control from American politicians and officials in
Europe, which is also contributing millions of dollars' worth of weapons.
Two categories of weapons in particular worry the State Department:
man-portable air defence systems, which include the thousands of Stinger
anti-aircraft missiles sent by the United States, and anti-tank/all-purpose
tactical guided missiles, which include the thousands of Javelins sent by
the United States.
According to the proposal, the State Department stated it is collaborating
with Kyiv to clear explosive combat debris, an action that would allow
"on-the-ground accounting for and securing of weapons."
Ned Price, a spokesman for the State Department, said in a statement that
"as in any conflict, we remain vigilant to the possibility that criminal and
non-state actors may attempt to illicitly acquire weapons from sources in
Ukraine, including members of the Russian military, during or after the
conflict."
