Heavy rainfalls and continued fighting exacerbate South Sudan crisisListen /
Humanitarian agencies say the crisis is worsening in South Sudan where fighting between rebels and the government has displaced hundreds of thousands of people.
The United Nations and the International Committee of the Red Cross say as the rainy season approaches millions face the risk of starvation.
The lack of security is also affecting thousands of Sudanese refugees living in settlements in disputed border areas.
