The Disasters Emergency Committee (DEC) have launched the Ukraine Humanitarian Appeal to raise funds for food, water, medicine, protection and trauma care for people fleeing the war.
This is one of the best appeals to give to because every pound donated by the UK public to the DEC will be matched by the government, up to the value of £20m. You can donate at a Post Office, as well as directly.
The UN Refugee Agency estimates that about 660,000 refugees have fled Ukraine to neighbouring countries. In Poland, it is providing new arrivals with information and legal services through a local legal partner.
Where possible, it is liaising with community leaders in Ukraine to assess their humanitarian needs and also delivering essential aid to internally displaced people.
The British Red Cross has its own appeal as well as being part of DEC. Alongside supporting people in Ukraine, donations will help its teams on the Polish, Slovakian, Romanian, Hungarian, Moldovan and Lithuanian borders to provide accommodation, food, water and other aid items to refugees.
Save the Children is distributing essential supplies and winter kits of clothing and blankets, providing cash and financial assistance to families to meet basic needs such as food and medicines, and offering mental health support to children and their families.
It suggests that a donation of £12 could help a victim of the violence access legal help or safe shelter.
