Sudan leader says he will teach independent South a 'final lesson by force'

Reuters reports — Sudanese warplanes carried out air strikes on South Sudan on Monday, killing three people near a southern oil town, residents and military officials said, three days after South Sudan pulled out of a disputed oil field.

A Reuters reporter at the scene, outside the oil town of Bentiu, said he saw a fighter aircraft drop two bombs near a river bridge between Bentiu and the neighboring town of Rubkona.
