Rome. January 29. INTERFAX - NATO's response to the development of the situation around Ukraine may follow due to a number of factors, Alliance Secretary General Jens Stoltenberg said.
"We can talk about a full-scale invasion, with the participation of tens of thousands of military personnel, with the use of artillery, missiles. However, there is also a possibility of attacks of a different kind: about undercover operations, sabotage, coups, serious cyber attacks," he said in an interview with the Italian newspaper Stampa, answering the question about what actions of Russia in Ukraine are capable of provoking a NATO reaction.
