In Ukraine, at least 13 people have been killed and more than 70 others have been injured in the past day, according to local officials.
Among them are four people who died after Russian drones struck a dairy factory outside the Ukrainian capital, Kyiv, according to the regional head.
Deaths and injuries from Russian strikes were also reported in Kherson, Kharkiv, Sumy, Zaporizhzhia, Chernihiv and Dnipro regions.
Ukrainian President Volodymyr Zelensky said food warehouses, a postal building and a school were among the other facilities that were hit.
On Thursday, he called for a face-to-face meeting between himself and Vladimir Putin in a renewed bid to end the war.
In an open letter to the Russian president, Zelensky said it would be “wrong to simply wait” until the war in Europe becomes the focus of the US’s attention once more, adding peace could only come “through direct engagement between” Ukraine and Russia.
He also called for a full ceasefire for the duration of proposed negotiations – something Putin ruled out earlier on Thursday.
The Kremlin confirmed it had received the letter. Spokesman Dmitry Peskov told Russian state newspaper Izvestia that it was likely Putin would comment on it on Friday.
The European Union, France and the US are among those that have backed Zelensky’s calls for a meeting.
“I think it would be great if they met. They should. Get it done,” US President Donald Trump told reporters on Thursday.
“I want them each to make certain compromises, and I think they’re going to do it.”
