Sudan's President will travel to South Sudan on Friday, his office says

Sudan's President Omar al-Bashir will travel to South Sudan on Friday, his office said, in a further sign of easing tensions between the two neighbours which fought along their common border last year.

'It's confirmed that President Bashir will visit Juba this Friday,' Emad Sayed Ahmed, the presidential press secretary, told AFP on Tuesday.

He had no further details about the trip, which will be Bashir's first since he attended South Sudan's independence celebrations on July 9, 2011, following a near-unanimous referendum vote for separation after a 22-year civil war.

A South Sudanese embassy official in Khartoum also confirmed the visit.

'I think he will meet high officials within the country,' the official said.

Independence left key issues unresolved, including how much the South should pay for shipping its oil through Sudanese pipelines for export.

South Sudan stopped all of its crude production early last year, cutting off most of its revenue after accusing Khartoum of theft.
