Several Wounded as Gunmen Attack Civilians in S.Sudan U.N. Base

Several people were wounded in South Sudan Thursday after gunmen attacked civilians sheltering inside a U.N. peacekeeping base in the war-ravaged town of Bor, the U.N. said.

The top U.N. aid official in South Sudan, Toby Lanzer, said he was "outraged" by what he said was an "attack of armed youth in Bor on civilians seeking protection".

Almost 5,000 civilians are sheltering inside the fortified base of the U.N. mission in South Sudan (UNMISS) in the town, one of the most bitterly contested regions in the four-month long conflict in the world's newest nation.

Mayor Nhial Majok said at least 14 people were wounded, but added that the number could be more.

"Local youth were demonstrating... there was shooting of guns," Majok told Agence France Presse, adding that at least 14 young men had been seen with gunshot wounds.

Majok said the demonstrators had clashed with peacekeepers inside the base, but it was not immediately clear who had fired the shots.

"Some of the youth were armed," Majok said, adding that the situation was now "returning to calm".

The conflict in South Sudan has left thousands dead and forced around a million people to flee their homes since fighting broke out on December 15 in the capital Juba before spreading to other states in the oil-rich nation.

Over 67,000 civilians are still seeking U.N. protection from ethnic attacks.

"We will not be deterred," Lanzer added.

The fighting is between soldiers loyal to President Salva Kiir against mutinous troops who sided with Riek Machar, sacked as vice-president in 2013.

The conflict has also taken on an ethnic dimension, pitting Kiir's Dinka tribe against militia forces from Machar's Nuer people.

Bor town, capital of Jonglei state, has swapped hands several times during the conflict.

U.N. Secretary General Ban Ki-moon has warned that more than one million people were at risk of famine in the troubled country.
