KHARTOUM - Sudan's army accused South Sudan on Saturday of having troops on its territory, a sign tensions between the former civil war foes were unlikely to cool despite an international ultimatum to end fighting.

Sudanese army spokesman al-Sawarmi Khalid said the military would abide by a UN-backed African Union call to halt hostilities, in an effort to end weeks of border fighting that has threatened to escalate into a full-blown war.

But Khalid said the army had a right to defend its territory from foreign troops.

"We have committed to (the decision). And no shot has been fired from our side and no attacks or raids have been launched ... towards South Sudan," Khalid told Reuters.

"But we have to point out that we are still affected by the presence of the South Sudanese army inside our territories in some areas," he said, naming Kafen Debbi and Samaha in south and east Darfur.
