Russian special forces have killed eight militants, including two regional commanders of insurgent groups, in the country's North Caucasus region, officials said on Saturday. Security forces launched two operations late on Friday, said Russia's National Anti-Terrorism Committee (NAK). The two commanders killed, Islam Magomedov, 28, and Arsen Magomedov, 29, have been on the special forces' wanted list since 2010, an NAK spokesman in Moscow told Reuters. They were responsible for several attacks, including bombings, against civilians and law-enforcement officers, the spokesman said. "Seven militants, including two local leaders, have been eliminated in a fire exchange in the Kayakent and Sergokala districts of Dagestan," the spokesman said. The eighth militant was killed during an operation in the Kabardino-Balkaria region, he said.
