Mr Skripal, 66, and his daughter Yulia, in her 30s, are critically ill in hospital after being found unconscious in Salisbury, Wiltshire.
The foreign secretary said he was not pointing fingers at this stage, but described Russia as "a malign and disruptive force".
Russia has denied any involvement.
Counter Terrorism Police have taken over the investigation from Wiltshire Police.
But in a statement, the unit said the inquiry had not been declared a terrorist incident and there was no risk to the wider public.
Mr Skripal - a former Russian agent convicted of spying for Britain - and his daughter were found slumped on a bench outside a shopping centre on Sunday afternoon.
Earlier they were seen walking through an alley leading from a Zizzi restaurant, which has now been "secured" by police. The Bishop's Mill pub has also been cordoned off "as a precaution".

Scientists at Porton Down - the UK's secret weapons research facility in Wiltshire - are studying the "unknown substance" that is thought to have made the pair ill.
Mr Johnson told MPs: "Honourable members will note the echoes of the death of Alexander Litvinenko in 2006.
"And while it would be wrong to prejudge the investigation, I can reassure the House that should evidence emerge that implies state responsibility, then Her Majesty's Government will respond appropriately and robustly...
"I say to governments around the world that no attempt to take innocent life on UK soil will go unsanctioned or unpunished."
Mr Johnson said that if it emerged Russia was linked to the incident in Salisbury "it would be very difficult to imagine" that UK representation at this summer's football World Cup could go ahead in the "normal way".
The Football Association said it believed this was in reference to a UK government presence in Russia during the tournament and not in relation to the England football team.
