Vladimir Putin warns of 'lightening response' if anyone intervenes in Russia's Ukraine operation

Last week, Russia had successfully tested its state-of-the-art RS-28 Sarmat inter-continental ballistic missile

Moscow: Russian President Vladimir Putin has warned outside forces against interfering in the Ukraine conflict, promising a "lightning-speed" response to such actions, with the use of Moscow's most advanced weaponry.

"If someone decides to intervene in the ongoing events from the outside and create unacceptable strategic threats to us, they should know that our response to those oncoming blows will be swift, lightning-fast," Putin said in an address to lawmakers on Wednesday, RT reported.

"We have all the tools to do this. Tools that no one except us can brag about. But we`re not going to brag. We`ll use them if such a need arises," the President said, without specifying which tools could be deployed.

Russian authorities have already made all necessary decisions to prepare for such a response, he added.

Last week, Russia had successfully tested its state-of-the-art RS-28 Sarmat inter-continental ballistic missile. The new nuclear-capable missile can carry several Avangard hypersonic gliders, which are said to be able to bypass any existing air defence due to their extreme speed and ability to make constant maneuvers during their flight, RT reported.
