WASHINGTON (CNN) -- American fighter jets intercepted two Russian bombers, one of which buzzed a U.S. aircraft carrier in the western Pacific on Saturday, U.S. military officials told CNN Monday.
Russia's Defense Ministry said Tuesday that there was no violation of flight regulations during the incident. A ministry official said the flights are standard operating procedure for air force training.
One of them twice flew about 2,000 feet over the deck of the USS Nimitz Saturday while another flew about 50 miles away, officials said. Two others were at least 100 miles away, the military reported.
U.S. defense officials said four F/A-18A fighter jets from the Nimitz were in the air.

Russian bombers have been making flights over the western Pacific for several months.
There have been eight incidents off Alaska since July. Among the latest, on September 5, six F-15s from Elmendorf Air Force Base, adjacent to Anchorage, Alaska, intercepted six Russian bombers about 50 miles from the northwest coast of Alaska.
Two similar incidents occurred in August, one near Cape Lisburne, Alaska, and the other near Cold Bay, Alaska, west of the Aleutian Islands. E-mail to a friend
