Yemen says it has arrested the suspected mastermind of the spectacular attack on the intelligence headquarters in the country's main southern city that freed detainees and left 13 people dead. An official statement Sunday said the suspect belongs to “terrorist groups” in Yemen and has a known criminal record, including a bank robbery last year. The government had said the Saturday attack on the heavily protected security complex in the port city of Aden bore the hallmarks of Al-Qaeda. Meanwhile, Yemeni officials say gunmen from a southern separatist movement ambushed a military convoy, killing two officers. The early Sunday ambush in the southern Dali province is the latest salvo in increasingly violent standoff between the government and a southern separatist movement. The ambush is most likely unrelated to the attack by four gunmen on the Aden intelligence headquarters Saturday. Officials said a number of the attackers also died in the ambush.
