19 American based human rights organizations have urged US President Barrack Obama to push for additional sanctions in South Sudan and to support regional efforts to enforce existing ones.

Mr Obama is expected in Nairobi tomorrow.

The organizations say there are individuals who continue to undermine the peace process and organize attacks against civilians.

In a statement, the Enough Project and the organizations say the additional sanctions should include a UN arms embargo.

They “Urge Kenya and Ethiopia to share intelligence and contribute actively to the Asset Recovery Inter-Agency Network for Eastern Africa to jumpstart efforts to trace, seize, freeze, and return the proceeds of corruption to the people of South Sudan’.

It says that Obama’s visit to the region will provide an opportunity to discuss with regional heads of state the need to speed up the peace process.

The organizations also urge regional leaders to pressure all parties to the conflict immediately stop obstructing the delivery of humanitarian aid to areas affected by violence.
