In Russia, at least 12 people, including a top local police official, have been killed by two suicide bombings in the North Caucasus republic of Dagestan. The first blast took place outside the offices of the local interior ministry and the FSB security agency in the town of Kizlyar. Dagestani Interior Minister Rashid Nurgaliyev said the suicide bomber detonated his explosives when police tried to stop his car as he drove into the centre of the town. Twenty minutes later, another bomber wearing a police uniform blew himself up as police, emergency services personnel and residents gathered at the scene. The investigative committee of Russian prosecutors said a total of nine police officers were among the dead including the town's chief of police and twenty-three people were injured. Following today's attacks, the authorities have ordered police to increase security at official buildings across Dagestan, as well as at places where crowds gather, including schools, colleges and cinemas. The incident comes two days after 39 people were killed in two suicide bombings on the Moscow Metro.
