Russia's assault on Ukraine's power grid has targeted not just Kyiv, but the entire country. A mass attack on Feb. 7 damaged facilities servicing Ukraine's nuclear power plants and damaged thermal power plants far from the front lines.

KYIV, Ukraine (AP) — Russia launched a barrage of ballistic missiles and drones at Ukrainian cities in overnight attacks, officials reported on Thursday as Ukrainian President Volodymyr Zelenskyy said Moscow was “hesitating” about another round of U.S.-brokered talks on stopping the fighting.

Russian strikes early this morning cut heating to nearly 2,600 residential buildings in Kyiv, in a nationwide attack on energy facilities that killed two people in eastern Ukraine.

Russian forces have attacked Kyiv with ballistic missiles. An air-raid warning has been issued in the capital and a number of oblasts.

The assessment, which couldn’t be independently verified, could bolster Kyiv’s aim to drive up the cost for Moscow. Despite heavy casualties, Russian forces have made little significant progress on the battlefield,
