Russia’s hybrid warfare could push Nato to trigger its mutual defence clause, according to the head of Germany’s foreign intelligence service. Moscow is not in direct conflict with the West right now but that could change if Russia continues its acts of sabotage.

Russia's extensive use of hybrid measures against western targets increases the risk that NATO may eventually consider invoking the alliance's Article 5 mutual defence clause, the head of Germany's foreign intelligence service said.
