A residential building and a barn in the village of Poroz were "completely burned down" in the attack, Governor Vyacheslav Gladkov said, TRT reports.

Another residential building was severely damaged. "As a result of the release of two explosive devices, a private residential building caught fire. Tragically, two civilians died — a woman who was recovering from a fractured femur and a man who was caring for her," Gladkov wrote on Telegram.

"The son of the deceased managed to run out of the burning house at the last moment." He said rescue workers were on the scene, and a walkthrough of the area would be conducted during daylight hours.

Semyon Eremin, a war correspondent for the Russian daily Izvestia, has been killed in a drone attack in southeastern Ukraine, the daily said.

Izvestia said Eremin, 42, died of wounds suffered when a drone made a second pass over the area where he was reporting in Zaporizhzhia region.

It said Eremin had sent reports from many of the hottest battles in Ukraine's eastern regions during the 25-month-old war, including Mariupol, besieged by Russian troops for nearly three months in 2022.

He had also reported from Maryinka and Vuhledar, towns at the centre of many months of heavy fighting.
