Fighting has resumed in Ukraine's Kherson region after a six-day truce, the longest of Russia's full-scale invasion, allowed hundreds of people to be evacuated from the Russian-occupied town of Oleshky, according to the BBC.

Local Ukrainian authorities said on Monday that Russia had struck a medical facility in Kherson city centre. They also said a 62-year-old woman and a 73-year-old man were injured when a Russian drone attacked their car.

Ukraine's General Staff accused Russian forces of using the humanitarian pause to rotate units, expand anti-drone equipment on roads and deliver ammunition. Kremlin spokesman Dmitry Peskov said it was "reasonable to assume" the Ukrainian army also used the period to regroup, calling this "a completely standard practice."

The ceasefire was brokered by US First Lady Melania Trump, according to the report. Both Kyiv and Moscow thanked her, but no details of her involvement were shared.

Russia's human rights ombudsman, Yana Lantratova, and Ukraine's counterpart, Dmytro Lubinets, oversaw the truce and travelled into Oleshky together. Both called for similar ceasefires elsewhere. Peskov said on Monday there were "no similar plans or initiatives," and described Oleshky as "an isolated case."

Hundreds of evacuees arrived in northern Ukraine on Saturday, many meeting relatives they had not seen in years. Lantratova said residents who stayed behind will receive monthly humanitarian aid deliveries.

Ukrainian drones also hit several energy facilities across four Russian regions, the report says. In Samara, an oil refinery was hit for the fifth time in a month.
