“Ukrainian soldiers had to ration ammunition due to dwindling supplies,” US President Biden says in pushing for approval of more American aid.

Russia on Sunday said it had complete control of the Ukrainian city of Avdiivka after Kyiv withdrew its forces from the area, in what appeared to be Moscow’s biggest success in nine months.

Ukrainian President Volodymyr Zelenskyy said Ukrainian commanders had decided to retreat from the besieged city in the face of relentless “meat wave” attacks by Russian troops.

Speaking at at the Munich Security Conference on Saturday, Zelenskyy referred to an “artificial deficit” in ammunition and renewed his calls for faster deliveries of artillery shells and long-range missiles.

U.S. President Joe Biden said “Ukrainian soldiers had to ration ammunition due to dwindling supplies as a result of congressional inaction, resulting in Russia’s first notable gains in months.” Biden called on lawmakers to approve $60 billion in aid to Ukraine that has been held up in the U.S. Congress.
