The death toll of the inter-communal fighting at the UN camp in Malakal has risen.

On Thursday, Eastern Nile authorities reported that three of the wounded people who were taken to a hospital died while five were killed inside the UN camp.

However, MSF says 18 people, including 2 of its staff, have been killed in the violence which erupted in on Wednesday and continued until Thursday.

“Youth from two particular communities in the camp clashed at the base, using machetes, sticks and guns, according to the UNMISS and state government officials. The cause of the clashes is not clear.

In a statement, the medical charity says the two staff were attacked in their homes inside the camp.

It says its hospital in Malakal has treated 36 people who were wounded in the incident. 25 patients had suffered minor gunshot wounds and eight others required surgery.

MSF says more casualties are continuing to arrive at their facilities.

“This attack on civilians is outrageous and we demand that armed groups stop these actions,” said Marcus Bachmann, coordinator of MSF projects in South Sudan.

“People came to the PoC looking for protection and this should be a sanctuary respected by all parties.”

The humanitarian group says the violence initially forced about 600 people, mostly women and children, to leave their tents and gather inside the hospital.
