(Newser) – An old war is returning to the world's newest country. Sudanese warplanes bombed two towns across the border in South Sudan today, inching the two countries, former civil war opponents, closer to full-scale war, CNN reports. At least three people were killed. "I can see market stalls burning in Rubkona in the background and the body of a small child burning," a Reuters correspondent at the scene said.

The neighboring countries have clashed repeatedly in recent months over oil revenues and a disputed border, the AP notes. Today's attack comes days after South Sudan withdrew its forces from Heglig, the oil-rich border town its troops entered two weeks ago, at the request of the United Nations Security Council. On the weekend, President Obama urged both side to "choose peace" and return to negotiations.
