LONDON -- A third person has been accused in connection with the 2018 Novichok poisonings in the English cathedral city of Salisbury.

Counter-terrorism police have recommended charges against Sergey Fedotov -- an alias for Denis Sergeev -- including conspiracy to murder, attempted murder as well as possession and use of a chemical weapon.

Authorities believe he is a member of the Russian military intelligence service, the GRU.

British authorities had previously charged two Russian nationals, Anatoliy Chepiga and Alexander Yevgenyevich Mishkin, over the poisonings of former GRU officer Sergei Skripal and his daughter Yulia Skripal.

The nerve agent later killed a 44-year-old local woman, Dawn Sturgess, who had inadvertently sprayed herself with a perfume bottle containing the substance.

Scores of migrants were rescued off the northern coast of France as they were trying to reach England, French authorities said on Tuesday. -- Euronews
