European countries that continue to buy Russian oil, according to Ukrainian President Volodymyr Zelensky, are “earning their money in other people’s blood.”

President Zelensky singled out Germany and Hungary in an interview with the BBC, accusing them of obstructing efforts to impose an embargo on energy shipments, from which Russia stands to profit up to £250 billion ($326 billion) this year.

Ukraine’s government has grown increasingly frustrated with Berlin, which has approved some sanctions against Russia but has so far rejected calls for harder action on oil sales.

“Some of our friends and partners understand that it is a different time now, that it is no longer an issue of business and money,” Mr. Zelensky told the BBC from his situation room in Kyiv on Thursday. “That it is an issue of survival.”

The United States, the United Kingdom, some European countries – they are trying to help and are helping,” the president said. “But still we need it sooner, sooner and faster. The key word is now.”

In recent weeks, Russian troops have pulled back from Kyiv, Ukraine’s capital, as well as other central and northern sections of the nation, indicating that they have abandoned their plan to take over the entire country by force.
