Peacekeepers in Sudan's Darfur region say at least six people have been killed during clashes at a refugee camp.

Peacekeepers from the joint United Nations-African Union mission say gunfire broke out Saturday at the Hamidiya camp in West Darfur state.

It is not clear who was involved in the violence.  Rebels say government forces attacked the camp for displaced people. However, other accounts say the clashes were between different groups in the camp.

Peacekeepers said they do not know who was behind the fighting.

Friday, rebels in Darfur from the Sudan Liberation Army accused the government of launching an attack in the rebel-controlled Tabra district.  Rebels said more than 50 people at Tabra market were killed and more than 150 others wounded in those attacks.

The French news agency quotes a Sudanese army spokesman as saying the SLA claims are "completely baseless," and that there have been no clashes between the army and the rebels.  

Darfur has endured more than seven years of violence since rebels rose up against Sudan's government, accusing it of neglecting the region.  The United Nations says more than 300,000 people have been killed and 2.7 million displaced from their homes.  Sudan's government puts the death toll much lower, at 10,000.

The International Criminal Court has indicted Sudanese President Omar al-Bashir for alleged war crimes in the region.
