Sudanese warplanes bombed a market and an oil field in South Sudan, killing at least two people hours after Sudanese ground forces reportedly crossed into South Sudan with tanks and artillery, elevating the risk of all-out war between the two old enemies. Al-Bashir vowed Monday to press ahead with his military campaign until all southern troops or affiliated forces are chased out of the north.(AP Photo) less
