A photo taken on April 6, 2018 shows a view of the Kremlin towers and cathedrals in Moscow. Moscow rejected on April 6 a British news report that the nerve agent used in the poisoning of a former double agent originated from a town on Russia's Volga river. Britain blames Russia for the March 4 poisoning on UK soil of former double agent Sergei Skripal and his daughter Yulia with what it says was a Soviet-made military-grade nerve agent, a charge the Kremlin furiously denies. / AFP PHOTO / Mladen ANTONOV
