More than 50 people have been killed in fighting between a new rebel group and government troops in a remote town in South Sudan, East Africa, and the "smell of dead bodies" is in residential areas, a church official said on Wednesday.
Humanitarian coordinator of the Caritas Diocese of Wau, Moses Peter, said he had seen 50 bodies at a mortuary in Wau town, which is about 650km northwest of the capital, Juba.
Thousands of people are sheltering at church and aid group sites and the local UN peacekeeping base, Peter said.
"The army, which is patrolling the streets here, has asked people to return to their homes but the displaced are still in fear," he said.
"They do not want to return to their homes because they do not trust the army, because they say it is the army that killed civilians."
South Sudan's government said on Tuesday a new rebel group had formed only months after the leader of another rebel group signed a peace deal to end a civil war.
The new rebel group has an Islamic fundamentalist agenda and includes former government troops, fighters from the Ugandan-led rebel group the Lord's Resistance Army and a Sudanese militia called the janjaweed.
Relief agencies are providing emergency assistance to displaced people in Wau following intense fighting on Friday and Saturday, according to the International Organization for Migration.
