KHARTOUM - A train carrying southern Sudanese migrants was attacked in the country's conflict-stricken Southern Kordofan border state on Sunday, killing at least one person, the United Nations said.
UN spokeswoman Hua Jiang said the most recent information indicated armed Misseriya tribesman were behind the attack. A senior Misseriya official denied the tribe had a role in the attack, and blamed it on rebels from neighboring Darfur.
South Sudan will declare independence on July 9, but fighting in the vaguely-defined border region has complicated the split and raised fears of a broader conflict.
Many southerners are trying to return home ahead of the secession, which sometimes involves crossing through volatile areas.
