Conflict in Ukraine escalated on 24 February 2022 when the Russian military entered into the country. Heavy fighting is currently taking place throughout the country, particularly in Kharkiv, Chernihiv, Kherson, Mariupol, Mykolaiv, Odesa, Donetsk and Luhansk. regions. Fighting is resulting in civilian casualties and significant damage to infrastructure and buildings, especially in Mariupol and Chernihiv cities.? 

Insecurity is forcing people to leave their homes; most of them are women, children, and elderly people, as men between 18–60 are asked to stay and fight. More than six million refugees from Ukraine are either in neighbouring countries (such as Slovakia,  Hungary, Moldova, Poland, Romania, and Russia) or have travelled further to other countries. Over 8 million people are estimated to be displaced within Ukraine, and numbers are expected to continue increasing because of the hostilities. Around 13 million people are estimated to be stranded in affected areas. Some people chose to stay or were unable to flee and are hiding in basements or subway stations. The movement of civilians is limited because of shelling and mines planted along roads, which hinders their access to basic goods and services. Shelling has also led to water and electricity cuts. Safe evacuation of civilians from besieged areas is facilitated through humanitarian corridors, which are often temporary and subject to change.?

People in need of humanitarian assistance have increased from 2.9 million before the 24 February escalation to 15.7 million after the escalation, with numbers expected to continue increasing because of continuing hostilities. About 24 million people are estimated to be affected by the conflict.?

Latest Developments


29/05: Over 260 attacks on healthcare in Ukraine were recorded between 24 February and 29 May. This number constitutes over 77% of the total attacks on healthcare worldwide in the same timeframe. Attacks on healthcare have damaged and destroyed health facilities and supplies, and killed and injured patients and personnel. Targeting healthcare affects people’s ability to access medical care, including those with injuries, pregnant women including those with obstetric emergencies, and people with non-communicable diseases, such as diabetes and cancer, needing ongoing treatment and care. Evacuation of patients and medical aid delivery to harder to reach areas, such as those with intense fighting, is challenging and people are facing shortages of medicines and medical supplies. About 50% of pharmacies in Ukraine are expected to be closed and many health workers cannot work or are displaced because of the fighting?.  Over 12 million people are estimated to need health assistance in Ukraine?.  

11/05: Around 890,000 people became internally displaced during April, bringing the total number of IDPs to over 8 million people. Increased fighting caused increased displacement in central and eastern macro-regions, while displacement decreased in other macro-regions. Around 2.7 million people have returned home after being displaced for at least two weeks since 24 February. IDPs especially need financial support and access to healthcare.?

25/05: There have been over 1,830 attacks on education facilities in Ukraine since the escalation of conflict including over 170 facilities completely destroyed. Over 50% of the attacks affected Donetsk, Kharkiv, and Luhansk oblasts. An estimated 3.3 million school-age children are in need of education assistance across Ukraine.?

25/05: The humanitarian situation in Ukraine deteriorated significantly following the Russian military offensive beginning 24 February, which has resulted in more than 3,940 civilians killed and over 4,590 injured, over 6.64 million people displaced to neighbouring countries including Poland, Hungary, Romania, Moldova and Slovakia, and over 8 million  people internally displaced as at 25 May.? Heavy fighting is reported throughout the country, particularly in Kharkiv, Chernihiv, Kherson, Mariupol, Mykolaiv, Odesa, Donetsk and Luhansk. Shelling and heavy artillery has led to severe damage of buildings and infrastructure such as roads, water, sanitation, and electricity.? The population is in urgent need of food, water, medical care, shelter, and protection. Humanitarian access is extremely constrained in areas affected by ongoing clashes.?

Humanitarian Access



Humanitarian access in Ukraine has deteriorated significantly and has become extremely constrained since the military escalation on 24 February. Fighting and shelling prevent people from moving freely and safely to where humanitarian assistance is available across the country, at the western borders, and through humanitarian corridors. Violence is affecting public services, such as hospitals, schools, and other civilian facilities, leading to demolishment or damage caused by shelling. People in besieged areas (such as Mariupol) are reported to have limited access to water, food, energy, and humanitarian corridors.? 

Insecurity has led to the relocation of most humanitarian staff; only a few organisations are able to distribute emergency aid in Ukraine. The presence of landmines and explosive remnants of war, particularly in areas with violence, hinders people’s movement and adds security and physical constraints to the access to or delivery of humanitarian assistance. ?

Background: Before the February 2022 escalation


Tensions in Ukraine started at the end of 2013 in Kiev following the decision of former president Viktor Yanukovych to refuse an association agreement with the EU. Protests in different cities were severely repressed, and armed conflicts broke out in mid-May 2014 when Russia annexed Crimea and started backing separatists in the Donbas region of eastern Ukraine. Since then, the Ukrainian armed forces and the separatist forces have been fighting along a contact line separating government-controlled areas from non-government-controlled areas in Donetsk and Luhansk oblasts. Between 2014 and the end of September 2021, more than 3,000 civilians have died, and over 7,000 people have been injured because of the conflict in eastern Ukraine. Prior to the February 2022 escalation, 2.9 million people were estimated to be in need, mainly in eastern Ukraine. About 1.46 million people were displaced as at mid-December 2021.?

Key Priorities


WASH: About 13 million people are estimated to need access to safe WASH services in March–August 2022, with more people expected to be in need of WASH in the upcoming months. Shelling has damaged water treatment facilities, pipelines, and pumps, limiting repairs. Power cuts affecting water pumps and the inability to pay for hygiene products further aggravate WASH needs of the affected population.?

About 1.4 million people have no access to safe water in eastern Ukraine, and an additional 4.6 million have only limited access as a result of the conflict and attacks on water and electricity infrastructure.?

Food security and livelihood: About 10.2 million people are estimated to need access to food and livelihood services in March–August 2022, with more people expected to be in need of FSL in the upcoming months. According to early estimations, at least 29% of people in Ukraine are currently facing food shortages. There is increased reliance on coping strategies such as reducing food intake and the number of meals. The conflict has disrupted normal food supply chains. Farmers face challenges delivering their produce to markets because of fuel shortages and disruptions in commercial transportation.?

Health: About 12 million people are estimated to be in need of health and nutrition assistance in March–August 2022; this figure is likely to increase as a result of continuing hostilities. Power shortages, lack of medicines and medical supplies, understaffing, damaged infrastructure, and disruptions to water systems have affected the functioning of health facilities.?

Protection: About 15.7 million people are estimated to be in need of access to protection services in March–August 2022; this figure is likely to increase because of continuing hostilities. The conflict resulted in civilian casualties and displacements, as well as protection risks for the population, including human rights violations, human trafficking, sexual exploitation, limited freedom of movement (especially between non-government-controlled areas and government-controlled areas), and the presence of unexploded explosive ordnance (especially near the contact line).?

Shelter and NFI:  About 6.2 million people are estimated to be in need of access to shelter and NFI services in March–August 2022; this figure is likely to increase because of continuing hostilities. The conflict resulted in civilian casualties and displacements. At least 8 million people have been internally displaced, with some taking refuge in public spaces and reception centres with inadequate amenities. Many IDPs are located in western regions, which has strained public resources in these areas. The cost of rent in western regions has also risen, making accommodation unaffordable for many IDPs.?
