US allies accuse Russia of 'escalating hybrid activities' against NATO, EU nations after data cables severed

U.S. allies in Europe allege Russia is "escalating hybrid activities" against NATO and EU nations following the severing of two data cables in the Baltic Sea. 

The declaration comes as Moscow says Ukrainian forces have fired six U.S.-made missiles into Russian territory on Tuesday. In the two days beforehand, the cables linking Finland to Germany and Sweden to Lithuania were slashed underwater, according to Reuters. 

"No one believes that these cables were cut accidentally," German Defense Minister Boris Pistorius was quoted by Reuters as saying Tuesday. "We also have to assume, without knowing it yet, that it is sabotage."
