The European Union must discuss an import ban on Russian gas deliveries after Ukrainian and European officials accused Russian forces of committing atrocities near Kyiv, the German defence ministry said on Sunday.
"There has to be a response. Such crimes must not remain without a response," the ministry quoted Defence Minister Christine Lambrecht as saying in an interview.
Berlin has so far resisted growing calls to impose an embargo on energy imports from Russia, saying its economy and that of other European countries are too dependent on them. Russia supplies 40% of Europe's gas needs.
But Lambrecht said EU ministers would now have to discuss a ban, according to a tweet from her ministry.
Foreign Minister Annalena Baerbock on Sunday also called for tougher sanctions on Moscow but stopped short of mentioning the energy sector.
"Those responsible for these war crimes must be made accountable. We will tighten the sanctions against Russia and will assist Ukraine even more in defending itself," she said on Twitter.
The EU has been working on additional sanctions for some time but Economic Commissioner Paolo Gentiloni said on Saturday that any additional measures would not affect the energy sector.
Ukraine said on Saturday it had taken complete control of the Kyiv region for the first time since Russia launched its invasion on Feb. 24. The mayor of Bucha, a liberated town 37 km (23 miles) northwest of the capital, said 300 residents had been killed by the Russian army.
Russia's defence ministry denied the allegation, saying footage and photographs showing dead bodies in Bucha were "yet another provocation" by Kyiv.
German Chancellor Olaf Scholz called in a statement for international organisations such as the International Committee of the Red Cross (ICRC) to be allowed access to the affected areas to independently document what he described as atrocities.
