Six doctors, including a Venezuelan and two from the Philippines, were among 25 people killed in a suicide bombing and gun attack on Yemen's defence ministry complex Thursday, medical and security sources said. The death toll also includes three Yemeni doctors and five patients, among them a judge, at a hospital within the complex that took the brunt of the attack, a medic said. A security official told AFP the death toll of the brazen attack has risen to at least 25.
