The presidents of Sudan and South Sudan are meeting for a second day as they try to reach an agreement on long-standing issues remaining from their split last year.

The talks between President Omar al-Bashir of Sudan and South Sudan President Salva Kiir continued Monday in the Ethiopian capital, Addis Ababa.

A Sudanese spokesman said after an initial round of negotiations Sunday that the two sides mostly agreed on economic, oil and trade matters, but that they remained divided on security issues.

The disputes stemming from South Sudan's July 2011 independence from Sudan include dueling claims on the oil-rich Abyei region.

Sudan also accuses the south of arming rebels in two southern regions, while South Sudan accuses the Sudanese army of bombing raids.

The United Nations gave the two Sudans until this past Saturday to reach an agreement or face possible sanctions.
