Sergei Skripal and his daughter Yulia were believed to have been poisoned by two Russians in 2018. A third suspect has just emerged.

British police on Thursday released more video footage of the two suspects they believe poisoned former Russian spy Sergei Skripal and his daughter in Salisbury in March.

One of the two suspects in the poisoning of an ex-spy in England is a trained doctor who works for Russian military intelligence and traveled to Britain under an alias, investigative group Bellingcat reported Monday.
