Russian Ambassador to London Andrei Kelin said that Moscow is fully aware of the extent of Britain's involvement in the strikes on Russian air bases.
"This is a blow to strategic stability. Attempts to disrupt the strategic balance are a very serious phenomenon," the ambassador said in an interview with Sky News.
"A limited conflict must remain limited," escalation could provoke a "third world war," the ambassador warned.
Such attacks are carried out with the help of technology and data from Western countries, he stressed.
"London has not denied involvement. We are waiting for a certain reaction from London, but so far the only thing we have heard is the statement of the British Minister of Defense that they are going to supply Ukraine with 10 times more drones than before," Kelin said.
Kiev on June 1 carried out a terrorist attack with the use of drones against airfields in Murmansk, Irkutsk, Ivanovo, Ryazan, Amur regions. The attacks in the Ivanovo, Ryazan and Amur regions were repelled. Several units of aircraft caught fire as a result of terrorist attacks. There are no casualties among military and civilian personnel. Some participants of the terrorist attacks were detained.
