"We know who these people are; we have found them", Putin said at an economic forum in Vladivostok, Russia, Wednesday, according to the AP.
"We know who they are, we have found them", Putin said.
"They are civilians, of course", Putin said, contradicting the British government's assertion that they are officers of Russia's military intelligence agency, known as the GRU.
Putin urged the men to speak to journalists.
"We should stop expecting reasonable action from our so-called Western partners or wait for the conflict to settle soon by itself", Sergey Mironov said in a Tuesday statement.
"There is nothing special or criminal about it, I can assure you". "We'll see in the near future", he added.
British authorities announced last week that Russian nationals Ruslan Boshirov and Alexander Petrov allegedly carried out the poisoning of Sergei and Yulia Skripal in Salisbury, England, earlier this year using a deadly nerve agent.
Mr Skripal - a former colonel in Russian military intelligence who betrayed dozens of agents to Britain's MI6 foreign intelligence service - and his daughter were found slumped unconscious on a bench in the English city of Salisbury in March.
Britain's security minister, Ben Wallace, said on September 6 that Putin "ultimately" bears responsibility for the poisoning because "it is his government that controls, funds, and directs the military intelligence".
The Kremlin has repeatedly denied knowing about the poisoning.
Britain has said the two suspects were Russian military intelligence officers nearly certainly following orders from the Kremlin, which has denied any involvement in the incidents.
The Skripals spent weeks in hospital in a critical condition after the poisoning.
Two others also fell ill: Sturgess's boyfriend, Charlie Rowley; and police officer Nick Bailey.
UK Home Secretary Sajid Javid has warned the men, thought to be aged about 40, will be caught and prosecuted if they ever step out of Russian Federation.
The attack on Sergei Skripal, the former Russian spy, also poisoned another British man and killed a British woman.
