This was stated by US State Department spokesman Ned Price.
“We are worried that Moscow may use a potential pause in the battle to re-equip, regroup and attack again,” RIA Novosti quotes him as saying.
Price said Washington was skeptical of Russia's claims of a temporary ceasefire.
In accordance with the instructions of Russian President Vladimir Putin, the troops were ordered to cease fire along the entire line of contact between the parties in Ukraine for 36 hours from 12:00 on January 6.
In turn, Ukrainian leader Volodymyr Zelensky rejected Russia's proposal to establish a Christmas truce on January 6 and 7.
The Ukrainian armed forces fired on Donetsk at exactly 12:00, when the ceasefire established by Russia began to operate.
