The rebel Lord's Resistance Army has killed at least eight people in a new series of attacks in southern Sudan.

Local officials say LRA fighters attacked villages near Yambio, the capital of Western Equatoria state, on Friday and Saturday. They say all of those killed were civilians.

The LRA is originally from Uganda but has evolved into a roaming band of fighters causing terror across central Africa.

Last month, Human Rights Watch said the group had killed more than 250 people in the Central African Republic and the Democratic Republic of Congo over the previous year and a half.

It said nearly 700 others were kidnapped and forced to be either soldiers or sex slaves.

Ugandan forces have chased the rebels in neighboring countries but have failed to stop the attacks or catch LRA leader Joseph Kony.

Kony is wanted by the International Criminal Court for alleged crimes against humanity.
