A US Coast Guard helicopter crashed into the Bering Sea with 10 people aboard while conducting a rescue after a powerless bulk freighter grounded on an island in south-western Alaska. The Coast Guard cutter Alex Haley picked up four of the 10 people. Six were unaccounted for, the Coast Guard said. The Selendang Ayu, a 738ft-long freighter loaded with soybeans and 1.7 million litres of fuel, broke in two when it ran aground on Unalaska Island in the Aleutian chain, the Coast Guard said.
