JUBA - South Sudan on Friday accused Sudan of killing seven people in air strikes on a disputed area and said its northern neighbor was jeopardizing a plan to restart cross-border oil flows by massing troops along their joint border.
Sudan has already denied the accusations of bombing - which South Sudan said lasted for three days - and a Sudanese military spokesman was not immediately available on Friday to respond to the new troop movement allegation.
The African neighbors agreed to end hostilities in September and to resume oil exports from the South via the north after coming close to war in April, the worst outbreak of violence since South Sudan's secession last year.
But tensions flared up again this week after the two countries accused one another of failing to move their forces back from the unmarked joint border, something both had said must happen before oil exports could resume.
