A Ukrainian drone attack killed one person and wounded at least three others in southern Russia, a regional official said Saturday, with nearly 100 people fighting to extinguish a fire caused by the strike.

The attack damaged port installations in the Temryuk district on the Sea of Azov, near the Kerch Strait separating mainland Russia from the Crimean peninsula, which has been occupied by Moscow since 2014.

‘As a result of falling drone debris, a fire broke out at a maritime terminal... one person was killed,’ Krasnodar Krai governor Veniamin Kondratyev posted on Telegram.

He added that at least three people were wounded, according to first reports, and that 96 people had been drafted to fight the blaze.

The Russian army said it had shot down a total of 177 Ukrainian drones overnight.

Ukraine has stepped up its campaign of attacks within Russia in recent months, claiming fair retaliation for Moscow’s own massive bombardments across the more than four-year-long conflict.

Kyiv insists that the Ukrainian army first and foremost targets military installations and energy infrastructure, in a bid to deprive the Kremlin’s war chest of vital fossil fuel revenues.

The Russian-occupied Zaporizhzhia nuclear power plant in Ukraine was reconnected to the grid Saturday, nearly three days after a strike cut off its external electricity supply, the UN nuclear watchdog said.

Power was restored after repairs to a back-up line, carried out while a local ceasefire was in place, the International Atomic Energy Agency said in a post on X.

During the loss of external power, Europe’s largest atomic power plant had to rely on emergency diesel generators to maintain cooling for its reactors, the agency added.

The plant’s 19th loss of off-site power during the war between Russia and Ukraine, which began in February 2022, was caused by a strike late Wednesday on a substation.

‘Lasting almost three days, it was one of the site’s longest such loss of power events, underlining the extreme fragility of the electrical grid,’ the IAEA said.

The agency previously said no release of radioactivity had been detected and radiation levels remained normal.

The plant is now preparing to repair its main power line, which has been offline since March 24.

Zaporizhzhia lies close to the front line in southern Ukraine, and was captured by Russian troops in the early days of their invasion.

Moscow and Kyiv have repeatedly accused each other of risking a nuclear catastrophe with attacks near the plant.
