The airport in the central Ukrainian city was completely destroyed in the Russian attack, reports said.

Five first responders were injured in the attack when Russian missiles destroyed an airfield in the Ukrainian city of Dnipro.

“Another attack took place at Dnipro airport,” Valentin Reznichenko, governor of the central region of Dnipropetrovsk, said on Sunday.

“The airport itself and the infrastructure around it have been destroyed. The rockets have been flying,” Reznichenko said on Telegram.

A missile also hit a building in the city’s Pavlohrad district, and emergency workers were clearing infrastructure in the hit Zvonetsky town.

Reznichenko said the attack on the city of Dnipro, on the banks of the Dnieper River, intensified on Sunday.

The industrial city of one million has been targeted by Russian forces since the invasion, but has suffered no major damage so far.

Separately, Mikola Lukashuk, head of the Dnipro Regional Council, said five workers of the state’s emergency services were injured by the strike at the airport.

The Russian Defense Ministry said the missile fired overnight destroyed the Ukrainian military base in Zvonetsky, which had recently been “reinforced by foreign mercenaries.”

On Sunday, Ukrainian President Volodymyr Zelensky said on Twitter that he discussed possible additional sanctions on Russia in a phone call with German Chancellor Olaf Schultz. Zelensky has called for an embargo on gas and oil imports from Russia, but Germany has so far resisted pressure to do so.

Germany may stop importing Russian oil this year, Scholz said on Friday, but it will be harder to stop importing natural gas because the country needs to build infrastructure to import gas from alternative sources.

Russian oil accounts for 25 percent of Germany’s imports, down from 35 percent before the Feb. 24 invasion. Germany’s natural gas imports from Russia fell from 55% to 40%, and its hard coal imports fell from 50% to 25%.
