Russia is 'running out of munitions and has lost as much as 50% of its tanks' in Ukraine, senior US official says

• Russia lost some 50% of its tanks in the past year, US Deputy Treasury Secretary Wally Adeyemo said.
• He argued that US-led sanctions had succeeded in crippling Russia's economy and thus its war effort.
• However, data suggests that Russia's economy in 2022 shrunk less than initially forecasted.
  

Russia has lost up to half of its tanks in Ukraine since the start of the war and is running low on ammunition, a senior US official said.
