Top news: South Sudanese leaders say at least 23 people have been killed in clashes between tribespeople and Arab nomads on the north-south border as the region heads to the polls for a second day of voting on a weeklong independence referendum.
A Ugandan and a northern Army soldier were also arrested in the Southern Sudanese capital of Juba in possession of 700 rounds of AK-47 ammunition. The south has accused the north of arming Arab militias in the contested border region of Abyei in the run-up to the vote.
Elsewhere in Sudan, the atmosphere was reportedly peaceful and festive with long lines of south Sudanese coming out to vote. A 60 percent vote is needed for secession, which seems likely given the level of support for independence in Southern Sudan.
In a possibly major conciliatory gesture, former U.S. President Jimmy Carter says that Sudanese President Omar al-Bashir has offered to take on Sudan's full international debt if Southern Sudan secedes. Bashir has promised to respect the results of the referendum.
Final results are expecting on Feb. 15.
