London threatens Moscow over incident ex-spy

london - The British Foreign Minister, Boris Johnson, has promised Russia 'a strong and appropriate response' if it appears that the Kremlin has something to do with the attack on a former double-spy from Russia on Sunday.

66-year-old Sergej Skripal was found unconscious at a shopping center in Salisbury with his 33-year-old daughter Joelia.

They came into contact with 'an as yet unknown substance', according to the police. Both are in a critical condition in a hospital. Johnson warned 'that no attempt to rob the innocent of life in this country will go unpunished. 'Johnson, for example, was out loud about a boycott of the World Cup in Russia.

According to British media, the Skripals are reminiscent of the Aleksandr Litvinenko poisoned in England in 2006. He was a former colonel of the Russian secret service who was murdered with a very expensive nuclear substance.
