Russian strikes wound nine and damage Ukraine's power network ahead of talks

Zelensky added that beyond Kyiv, substations were damaged in Vinnytsia, Zhytomyr, Rivne, Kharkiv and Dnipro regions.

The latest attacks come after US First Lady Melania Trump hosted Russian and Ukrainian delegations at the White House on Thursday.

She called for a "more enduring" ceasefire in Ukraine following a truce last week in the southern region of Kherson.

She thanked both Zelensky and Russian President Vladimir Putin, making no reference to the origins of the war, which began when Putin launched a full-scale invasion of Ukraine in February 2022, which has caused thousands of civilian casualties and the displacement of millions.
