Russian forces have shelled the “entire front line” in the Donetsk region in eastern Ukraine, the region’s governor, Pavlo Kyrylenko, has said. The fiercest fighting was near the towns of Bakhmut and Avdiivka, he said, adding that Russian troops were also trying to advance near Lyman, which was recaptured by Ukrainian forces in November.

Russian forces have installed multiple rocket launchers at Ukraine’s shut-down Zaporizhzhia nuclear power plant, Ukrainian officials claimed Thursday, raising fears Europe’s largest atomic power station could be used as a base to fire on Ukrainian territory, heightening radiation dangers.

Ukraine’s state-run power agency has accused Russian forces of abducting two senior Ukrainian staff at the Russian-occupied Zaporizhzhia nuclear power plant. Energoatom said the two abducted members of staff were beaten before being driven off in an “unknown direction” on Thursday. A third worker, who was detained, was responsible for safety at the plant, it said.

Vladimir Putin has said “ultimately an agreement will have to be reached” to end the conflict in Ukraine, but said he was wary of doing so following the Minsk agreements. Russia’s president also acknowledged that there had been some problems supplying equipment and clothes to the 300,000 men who were conscripted to fight in Ukraine in recent months.

The US is preparing to send Ukraine a $275m military aid package offering new capabilities to defeat drones and strengthen air defenses, according to a document seen by Reuters on Thursday and people familiar with the package.

Russian shelling of a town in the Donetsk region in eastern Ukraine has left 1 person dead and 2 injured, according to the region’s governor, Pavlo Kyrylenko. At least 12 houses were destroyed by the shelling in the town of Toretsk, he said.
