Russian forces took full control of Ukraine's Soviet-era coke plant in Avdiivka Monday, days after Ukraine withdrew its troops from the town amid ammunition shortages.

"The 'Centre' grouping of troops, taking the offensive, took full control of the coke plant in Avdiivka," Russia's defense ministry said in a statement, according to Reuters. "Russian flags were hoisted on the administrative buildings of the plant."

Aerial footage released shows multiple blasts of what appeared to be the coal-based fuel plant.

The defense ministry said its troops advanced about 9 km (5 miles) in that area, with Russian troops continuing to advance forward, according to Reuters.

Ukraine withdrew its troops from the town Saturday as the country faced acute shortages of ammunition with U.S. military aid delayed for months in Congress. Kyiv said the withdrawal aimed to save troops from being fully surrounded by Russian forces after months of fighting.

Putin called the withdrawal a victory, congratulating Russian troops.
