Logistics and distribution are definitely challenges. As in any conflict, people who are displaced within the country itself tend to receive the least amount of assistance. Once people cross the border, they come under the international system for refugee protection and assistance. However, those who are internally displaced are often overlooked, since the conflict makes it difficult to access areas within the country.
For that reason, I can't give you any specific information on what is going on in the various regions of Ukraine. I can say, though, that food, protective services and supports for women who are victims of violence are harder to access within Ukraine than they are in neighbouring countries right now.
