Ukrainian forces hit a Russian base with over 30 strikes in the Russian-occupied southern city of Melitopol on Sunday, the city’s exiled Ukrainian mayor said.

A Russian official confirmed strikes had hit the city.

At 3 o’clock (1200 GMT) and 5 o’clock (0200 GMT), there were over 30 strikes exclusively on a military base,” Melitopol Mayor Ivan Fedorov, who is currently on Ukraine-controlled territory, said in a video address on Telegram, adding that the base had been “taken out of action.”

Fedorov also said that resistance activity had caused a Russian armoured train carrying ammunition to derail on Saturday near Melitopol.

Russia’s RIA news agency reported that Ukraine had hit the Aviamistechko area of Melitopol where the city’s airport is located, but did not specify what had been hit.

RIA cited local Russian-appointed official Vladimir Rogov as saying that around 16-18 Ukrainian MLRS rockets had hit Melitopol in two strikes at 0300 and 0445 Moscow time (1200 GMT and 0145 GMT).
