Baltic spy chiefs warn Moscow is preparing for more decisive action in Europe

Exclusive: intelligence officers warn campaign against Nato could intensify ‘in months, not years’ – but panic will play into Kremlin psy-ops

European intelligence officials have raised the possibility of an imminent Russian test of Nato, with one saying a potential attack could come in a matter of “months not years”.

The warnings came after Poland’s prime minister, Donald Tusk, told parliament that intelligence assessments suggest Russia may launch an attack with drones or missiles on Nato territory in the coming months, as part of efforts to prove that “article 5 is more theoretical than practical”.
