The Sudanese air force carried out a series of airstrikes on oilfields across the border in South Sudan's Unity state on Tuesday, South Sudan army spokesman Philip Aguer told RIA Novosti.
“The Sudanese Air Force delivered several airstrikes on oilfield areas in Unity state,” he said.
The attack comes a day after an armed clash in the border region, leading Sudanese President Omar Hassan al-Bashir to cancel a visit to South Sudan.
South Sudan won independence in July 2011 in a referendum that came as part of a peace deal to end decades of civil war. However, fighting still rages in disputed territory along the border with Sudan.
A series of recent tribal clashes in the country are believed to have left some 3,000 people dead.
