Vladimir Putin is warning NATO countries of tragic consequences if they were to send troops into Ukraine. 

The Russian President is referring to comments made earlier in the week by his French counterpart. 

Emmanuel Macron was speculating on opening the doors for European ground troops being sent to Ukraine. 

Europe Correspondent Vincent McAviney told Mike Hosking that following Sweden and Finland joining NATO, Putin feels the need to strengthen his defences. 

He says Russia would be ready to use their weapons offensively against other nations.
