Aid workers are becoming more concerned about the needs of the thousands of people who left home after violence in the African country of Kenya.
They say that up to 500,000 people have been affected by the unrest, with half of them deciding to leave their homes.
Many of them do not have food, water and shelter and the violence is making it hard for supplies to get through.
Meanwhile, talks to end the attacks - which were sparked by an election a week ago - are continuing.
Mwai Kibaki was re-elected president in the vote.
Violence broke out because many people thought the result wasn't fair.
Some Kenyans were so frightened that they moved away from their towns and villages.
Lots of them are living in camps in schools, hospitals and churches.
Aid workers fear that there will be an outbreak of diseases if medical help isn't delivered quickly.
