WASHINGTON (AP) — A Russian fighter jet intercepted an American reconnaissance plane in international airspace over the Pacific in late April, prompting top officials to complain to senior Russian military officials, a Pentagon spokesman said Tuesday.

Army Col. Steve Warren, the spokesman, said the Russian Su-27 fighter flew across the nose of the U.S. Air Force RC-135U aircraft, coming within about 100 feet, while in international airspace over the Sea of Okhotsk.
