Bulgaria on Tuesday rejected reports that the truck linked to the powerful blast that damaged Russia's bridge to annexed Crimea had travelled via its territory.
Alexander Bastrykin, the head of Russia's Investigative Committee, said that the vehicle had passed through Bulgaria, Georgia, Armenia, South Ossetia and Russia's Krasnodar region before arriving on the bridge.
"It has been indisputably established that the truck blown up on the Crimea bridge was never in the territory of Bulgaria," the government said in a statement.
