According to the outlet, Washington made the decision against the backdrop of reports of unidentified drones spotted in Poland, Norway, Sweden, and Denmark. Just last week, one of the Poseidons based in Oslo was dispatched to the Baltic Sea near the coast of Kaliningrad. Norwegian media reported that over the weekend several such aircraft were stationed at Oslo Gardermoen Airport.
