Russian security services say they have killed an Islamist rebel leader accused of plotting a failed terrorist attack in Moscow.
The militant leader, Ibragimkhalil Daudov -- also known as "Saleh" -- was reported killed on February 11 during a police operation in the Karabudakhkent district of Daghestan, in Russia's North Caucasus.
Three other militants were also reported killed in the operation.
Daudov had been on federal wanted lists for planning a suicide bomb attack in Moscow on New Year's Eve 2010.
The alleged plot reportedly was foiled when his wife was killed when the bomb she was assembling accidentally detonated hours before the attack was to occur.
Daudov was seen as active in arms trafficking, bombings, and extortion, and had led Daghestan's main militant group since April 2011, after its previous leader was killed.
