Militant groups believed to be affiliated with Al Qaeda were responsible for two attacks within 24 hours in south Yemen. At least 20 were killed when gunmen opened fire on the intelligence headquarters on Saturday, and on Sunday a suicide bombing took the life of a local anti-Al Qaeda militia leader. Attacks have continued since the country's Arab Spring uprising, when Al Qaeda-linked groups took control of certain areas but were pushed out by a U.S.-backed intervention.
