GENEVA/JUBA, Jan 24 An air strike on a refugee
camp near South Sudan's border with Sudan wounded one boy and
left 14 people missing on Monday, the U.N. refugee agency said.
South Sudan blamed the attack on Khartoum, which has
repeatedly denied carrying out such strikes on its neighbour.
South Sudan seceded from Sudan in July under a 2005 peace
deal that ended decades of civil war, but the two countries have
remained at loggerheads over issues including oil, debt and
fighting along the poorly drawn border.
Several bombs were dropped on Elfoj, a camp of about 5,000
refugees used as a transit site, less than 10 km from the border
on Monday morning, a spokeswoman for the U.N. High Commissioner
for Refugees (UNHCR) said in a statement on Tuesday.
"Definitely it is Khartoum forces ... there is no one else
who can bombard South Sudan's territory," a South Sudan military
spokesman said of the attack on Elfoj. "This is not the first
Rebels fighting Khartoum's forces said Sudanese government
helicopters and ground forces launched separate attacks on the
Sudan side of the border on the same day, although the report
was impossible to verify independently.
Sudan's military was not immediately available to comment on
either incident, but Khartoum has always denied carrying out
such attacks, including one on the Yida refugee camp in
November, which the United Nations blamed on Khartoum.
Fighting between Khartoum's forces and rebels from the Sudan
People's Liberation Army/Movement-North (SPLA/M-N) began in
June, before South Sudan became independent in July, and have
forced around 417,000 people to flee their homes and 80,000 to
cross the border into South Sudan, and into camps such as Elfoj.
The SPLM is now the ruling party in South Sudan but it
denies supporting SPLM-N rebels across the border.
The insurgency against Khartoum is a remnant of a two-decade
civil war in which many in Blue Nile and South Kordofan states
fought with those now ruling South Sudan but ended up falling
under Khartoum's control.
However, fighting around the border also feeds into wider
animosity over issues including the division of revenues from
oil from South Sudanese fields which is exported through Sudan.
UNCHR did not apportion blame. It moved 1,140 people from
the site, around 70 km (45 miles) to the south after the air
Details about what the South Sudanese spokesman described as
the attack on rebels in the south of Sudan were sketchy but a
U.N. source confirmed it had received reports of two helicopters
attacking the Ullu area near the border.
An SPLM-N spokesman told Reuters the settlement of Danfona,
just across the border from Elfoj, had been bombed.
"There is a big movement of Sudan Armed Forces
from (Blue Nile state capital) al-Damazin towards the Bau
mountains. They are coming with heavy weapons and air cover from
helicopter gunships," the spokesman told Reuters by telephone.
Tension between Sudan and South Sudan further
escalated on Monday when South Sudan began shutting down oil
production, accusing Sudan of stealing $815 million worth of
crude that it piped to its northern neighbour for shipment.
