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.

All Ukrainian troops have been forced from Russia’s Kursk region, Kremlin spokesperson Dmitry Peskov said Saturday. Ukrainian officials have not commented on the claim.

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