Airstrikes and ongoing conflict in Ukraine are leaving civilians - including thousands of children - without homes, power, water and basic services, as humanitarians warn the approaching winter is heightening the risks for communities along the frontlines.
Dozens of civilian casualties were reported over the weekend and into Monday, with children among the injured, according to UN Spokesperson Stéphane Dujarric.
The hardest-hit areas include Dnipro, Donetsk, Kharkiv, Kherson, Kyiv, Sumy and Zaporizhzhia.
"Meanwhile, our humanitarian colleagues tell us that evacuations of civilians continue from frontline communities in the Donetsk region," Mr. Dujarric told journalists in New York on Monday.
Between 24 and 26 October, more than 900 people were evacuated, he added, noting also that the Ukraine Humanitarian Fund has released $13 million since May to support local and national NGOs in the Kharkiv region, aiding nearly 76,000 residents.
Roughly half of those reached are women and girls. Assistance has included cash transfers, shelter, health services, water, sanitation, hygiene support and measures to prevent gender-based violence.
'You can't see anything'
Winterisation - providing lifesaving aid to vulnerable populations to protect them from cold weather and harsh conditions - is a major concern, the UN Children's Fund ( UNICEF ) warns.
Kenan Madi, Chief of Field Operations UNICEF Ukraine, told UN News that families along the frontlines urgently need heating, warm clothing and other essential supplies.
"The attacks on infrastructure are impacting basic services - from hospitals to water utilities to district heating - making everyday life extremely difficult for children," he said.
"I just had a colleague who came back from Chernihiv," he continued, adding: "The only thing he told me was, 'It's really dark - you can't see anything.' Some rural areas are in total blackout. That's what children are living through in Ukraine right now."
UN response
Amid these conditions, UN agencies continue their efforts to reach communities with aid. UNICEF has provided access to safe drinking water for 300,000 people in September alone and more than three million nationwide so far this year.
Education remains disrupted: approximately 350,000 children in frontline regions attend school in person, while over 400,000 follow a blended schedule and around 280,000 continue fully online.
To mitigate these disruptions, the agency supports over 150 learning centres offering catch-up classes, social-emotional support and safe learning spaces. It has also rehabilitated more than 100 schools and kindergartens since 2022, with 42 additional facilities under repair this year.
Mental health a priority
Mental health services are also a priority. Last month, UNICEF reached 16,000 children and 25,000 caregivers in frontline areas with psychosocial support and over 300,000 people have received mental health assistance throughout 2025.
Mr. Madi highlighted the human toll, referring to the challenges faced by a mother of twins who have autism.
"She deserves to get the help she needs, but this is not the story of one person alone. There are many households who are struggling with their daily lives. There are many stories on the front lines and unfortunately year after year it is becoming harder for the people, especially children, and this is something which is very worrying for us."
