A South Sudanese American has been on a hunger strike for 22 days in Washington DC.

Human rights activist Simon Aban Deng is demanding that US President Barack Obama’s administration takes more initiatives to bring peace in South Sudan.

Mr Aban calls on the international community to help the warring parties to start negotiating a lasting peace agreement.

“I am calling on Barak Obama to be a peace broker between the two warring parties in South Sudan because peace have to be essential to everybody regardless of whether we agreed with that peace or not,” Mr Aban argued.

“Stop the war and stopping killing one another. That is the goal and I’m going to remain on hunger strike until somebody says something.”

The South Sudanese government says Mr Aban should end the strike.

Foreign Ministry spokesman, Mawen Makol, says a strike of one man will not make any change in the peace process.
