Sudan has claimed three foreigners arrested in a disputed area on the border with South Sudan had military hardware and an armored vehicle. But a representative for one of the three said Sunday that they were on a humanitarian mine-clearing mission.
A Briton, a Norwegian, a South African and a South Sudanese were captured by Sudanese troops Saturday in the oil-rich region of Heglig.
The arrests are the latest sign of spiking tensions along the disputed border, where clashes have raged in recent weeks. The violence has brought the two nations, already at odds over demarcating the border and dividing oil revenue, to the brink of war.
