Rebel groups said Monday they had captured a Sudanese Army garrison near the border with South Sudan. The rebels said they killed 130 members of the government forces in the attack. The figure could not be independently verified. Sudan blamed the army of South Sudan for the attack, which took place on Sunday at a military post assault at Lake Obyad in South Kordofan Province, on the border with South Sudan. The rebel Sudan Revolutionary Front said it carried out the attack. South Sudan said none of its forces were involved.
