U.S. drone strikes have killed at least 10 people in central Yemen. Agence France-Presse said at least 20 people were killed in the overnight strikes targeting militants near Rada. Reuters put the toll at 10, but said 10 more people were killed in clashes between the targeted militant group Ansar al-Sharia and Shiite Houthi rebels. The rebels have taken over the Yemeni capital Sana’a and advanced south into majority Sunni areas. While recent attention has focused on the U.S. wars in Iraq and Syria, the United States has continued its covert bombardment of supposed militants in Yemen and Pakistan.
