On Monday, the UK police said that a man and a woman were found unconscious on a bench at a shopping center in Salisbury. Both of them were "in a critical condition" and are being treated for suspected exposure to an unknown substance. It was later confirmed by UK Foreign Secretary Boris Johnson that the man was Skripal, who was granted asylum in the United Kingdom after a US-Russia spy exchange, while the woman was his daughter, Yulia.
"Counterterrorism police, investigating the Salisbury suspected nerve agent attack, have identified over 240 witnesses and are looking at more than 200 pieces of evidence," Rudd said.
The secretary pointed out that police were carrying out a massive and substantial investigation.
In 2006, Skripal was sentenced in Russia to 13 years in prison for cooperating with the UK Secret Intelligence Service MI6 and transferring names of Russian intelligence agents working undercover in Europe. In 2010, then Russian President Dmitry Medvedev signed a decree pardoning Skripal, with the latter then moving to the United Kingdom.
Russian presidential spokesman Dmitry Peskov said that the Kremlin had no information on what could have caused the incident and noted that Moscow was open for cooperation.
