April 21 (UPI) -- For the fourth time in as many days, the U.S. military said it detected Russian military planes flying off the coast of Alaska, though they remained far away from penetrating U.S. air space.
The flights posed no danger to the United States, officials said, and did not prompt a U.S. military response. Earlier in the week, U.S. fighter jets were scrambled when Russian planes came 40 nautical miles from the coast of an Alaskan island.
