Tokyo, Sha'ban 12, 1437, May 19, 2016, SPA -- Japan lodged a protest with the US ambassador Thursday after a former US marine was arrested in connection with the disappearance of a woman whose body was found earlier in the day on Okinawa, according to dpa. The 32-year-old suspect, who is now a civilian employee at the US-operated Kadena Air Base on Okinawa, admitted involvement in the disappearance of the 20-year-old woman after police found DNA matching hers in his car, the island's newspaper Ryukyu Shimpo reported earlier. Japanese Foreign Minister Fumio Kishida called the US connection to the woman's death "regrettable," the Kyodo News agency reported. The arrest comes less than a week before US President Barack Obama arrives in Japan to attend the final G7 summit meeting of his presidency. He will see the coastal city of Shima and later visit Hiroshima, where the US dropped an atomic bomb in the closing days of World War II. --SPA 23:09 LOCAL TIME 20:09 GMT www.spa.gov.sa/w
