The US Navy has warned Japan that a nuclear submarine may have had radioactive leaks during recent calls in two of its southern ports. Japan's Foreign Ministry said Saturday that the U.S. Navy had told it that the nuclear-powered USS Houston submarine might have leaked a small amount of radiation during port calls in the southern Japanese naval ports of Sasebo and Okinawa in March and April.
