Russia’s Federal Security Service accused the man of planting an explosive device in the car, but said that it was detonated from Ukraine.

Russian security forces say they have detained a Ukrainian spy accused of killing a senior Russian general in a car bomb attack in Moscow's suburbs on Friday. The FSB secret service said they had apprehended "Ukrainian special services agent Ignat Kuzi" who had "planted explosives in a Volkswagen Golf" to kill Gen Yaroslav Moskalik.

Nearly nine months after losing chunks of the Kursk region to a surprise Ukrainian incursion, Russia has announced that its troops have fully reclaimed the border territory.

Ukraine denied that it had been pushed out of the region and said that its military operations inside Russia were continuing.

Russia has regained control of Kursk, the border region where Ukraine launched a surprise offensive last year, President Vladimir Putin said Saturday.
