  Among the ten largest ICRC deployments worldwide has been the mission in Ukraine, where the organization has been active since 2014, working closely with the Ukrainian Red Cross Society. At first, the ICRC was active primarily in the disputed regions of Donbas and Donetsk, assisting persons injured by armed confrontations there. When Russia invaded Ukraine on 24 February 2022, the fighting moved to more populated areas in East, North, and South Ukraine. The head of the ICRC delegation in Kyiv warned on 26 February 2022 that neighborhoods of major cities were becoming the frontline with significant consequences for their populations, including children, the sick, and elderly. The ICRC urgently called on all parties to the conflict not to forget their obligations under international humanitarian law to ensure the protection of the civilian population and infrastructure, and respect the dignity of refugees and prisoners of war.
  
  In response to events in the conflict, the organisation issued rule of engagement for civilian hackers.
