NATO allies said on Tuesday they would help Ukraine repair energy infrastructure heavily damaged by Russian bombardments in what NATO's chief said was Moscow using the descending winter cold as "a weapon of war".
Russia has been carrying out heavy missile attacks on Ukraine's power grid and heating infrastructure roughly weekly since October, in what Kyiv and its allies say is a deliberate campaign to harm civilians, a war crime. Russia acknowledges attacking Ukrainian infrastructure but denies deliberately seeking to harm civilians.
