“I was hit in my leg, when the soldiers started firing,” said Wiyual Chol, shot like many during a recent outbreak of fighting in Upper Nile state.

“I want to walk again, but it hurts,” he adds, struggling to sit up from his simple string bed.

Mr Chol is lucky - the treatment here is good, and many in the hospital took bullets in worse places than a leg.

Others lie with dressings plugging holes in their head or belly.

There have been a string of recent clashes in the south.
