Kristin Davis Breaks Down Describing Kenyan Refugee Camp Visit

Kristin Davis, better known as the eternal optimist Charlotte York on HBO's "Sex and the City," broke down sobbing while discussing with BBC the conditions in the Dadaab refugee camp in Kenya.

As droves of people flee drought and violence in Somalia, thousands of refugees have ended up in Dadaab, which has become severely overcrowded.

Davis, a humanitarian work campaigner, describes one woman's story to the BBC:

"This woman can't walk so she came from Somalia on her cart with a donkey. She started with five children and now she just has three who are there," Davis says, crying heavily. "Her husband was killed along the way, and they took everything she owned."
