NATO foreign ministers will gather Wednesday in Brussels to discuss support for Ukraine after mounting evidence of atrocities in a suburb of Kyiv spurred Western promises to step up economic pressure on the Kremlin.

The Biden administration is set to announce a ban on new investments in Russia and more sanctions, while the European Union, divided over imposing a full energy embargo, is debating an import ban on Russian coal under a new round of penalties. Ukrainian President Volodymyr Zelensky, demanding a tougher E.U. response Wednesday, criticized leaders who “still think war crimes are not as horrific as financial losses.”

Ukrainian leaders say the grim killings in Bucha are not the exception. The withdrawal of Russian forces in other parts of the country has revealed looted homes and shootings of civilians.
