Skripal Novichok poisoning: Russian suspects named

British prosecutors have charged two Russians with attempted murder after the Novichok nerve agent attack in Salisbury in March. Former Russian agent Sergei Skripal and his daughter Yulia were hospitalised after being exposed to the agent in March - and then in June one person died and another was hospitalised after coming into contact with the poison. Britain says the men responsible were using the names Alexander Petrov and Ruslan Boshirovand and are thought to be officers from Russia's military intelligence service.
