The Coordinator for Church Parliamentary Liaison accuses government forces of revenge killing in Wau.
Isaac Kenyi says so many people have taken refuge in Church compounds due to the conflict.
The Coordinator, who returned from Wau last week, told CRN that the people have no water and food.
Kenyi calls for quick respond to the situation and an end to the war.
The Coordinator calls on the warring parties to read the statement of the Catholic Bishops which calls for an end to the fighting.
Kenyi appreciates the combined forces deployed to Wau to bring the situation under control.
CRN could not reach SPLA to comment on the matter.
