Officials in Yemen say they've foiled a major terrorist plot to blow up oil pipelines and seize ports in their country. U.S. drone strikes killed seven suspected al-Qaida members yesterday in Yemen. This comes after U.S. authorities warned of possible terrorist attacks against Western targets. The U.S. shuttered more than a dozen American diplomatic posts across the Middle East and Africa. It also issued a global travel alert, citing security concerns. The U.S. precautions were prompted by intercepted communications between al-Qaida leaders in Pakistan and Yemen.
