When war breaks out families are torn apart, populations can be displaced or forced into exile, children become separated from their parents, and soldiers are wounded, taken prisoner, reported missing or killed in action. The ICRC and the National Red Cross and Red Crescent Societies work, often together with other humanitarian agencies, to alleviate the human suffering arising from these situations - in addition to other aid, this can include distributing Red Cross messages, organizing family reunifications, issuing temporary travel documents and capture cards and visiting persons deprived of their freedom.
