The Security Council passed a resolution by a unanimous vote last week that calls on Sudan and South Sudan to stop fighting and return to the negotiating table within two weeks.
South Sudanese Brig. Gen Gabrial Puok Wunoah said Sudanese forces dropped about eight bombs on a military base in Unity state late last week, the independent Sudan Tribune reports. A government spokesman alleges Sudanese forces also hit a separate army base about 15 miles away.
The Sudanese government issued a statement through its embassy in Washington declaring its commitment to the Security Council resolution.
Tensions escalated last month when forces from South Sudan seized oil fields in Heglig across the ill-defined border separating it from Sudan. Khartoum warned "provocations" from the south could leave it with no other option but "to invoke the right to self-defense."
South Sudan gained independence in July as part of a comprehensive peace agreement reached in 2005. The agreement ended one of the bloodiest wars in modern history, though South Sudan's seizure of disputed oil fields recently rekindled tensions.
