By Anne Kauranen, Essi Lehto and Andreas Rinke HELSINKI (Reuters) -NATO countries will deploy frigates, patrol aircraft and naval drones in the Baltic Sea to help protect critical infrastructure and reserve the right to take action against ships suspected of posing a security threat,

NATO announced on Tuesday that it will beef up its patrol of the Baltic Sea in the light of past infrastructure damage to cables on the sea floor.

The incidents contributed to mounting European fears of sabotage, as NATO officials accuse Russia of a growing “destabilization campaign” over their military support for Ukraine and sanctions against Moscow.
