Despite the fact that many of the attempts were thwarted at an early stage, terrorism remains a serious threat with terrorists using more diverse tactics, Putin said at a meeting of the Federal Security Service (FSB) Board.
It is necessary to better protect places of mass gathering, critical facilities and social institutions, and more effectively coordinate the work of the FSB and other security agencies, he said.
Putin ordered law enforcers to pay special attention to detecting the contacts between terrorist groups and foreign special services.
He praised the work of counterintelligence bodies, which have thwarted the activities of 72 employees and 423 agents of foreign special services last year.
The president also emphasized the importance of protecting military information and decreasing the chances of its leakage.
