US-Russia tensions flare in Baltic Sea

The Pentagon announced Saturday that it was filing a formal complaint with the Russian Defense Ministry and US Secretary of State John Kerry threatened retaliatory action after two incidents involving US and Russian forces in the Baltic Sea.
The Pentagon alleged that a Russian SU-27 fighter jet flew within 50 feet of a US reconnaissance plane in international airspace on April 14, and that a Russian jet and helicopter “buzzed” the Navy destroyer USS Donald Cook as it was conducting military exercises with Poland in the Baltic two days earlier.
