Manila: An American soldier accused of raping a Filipina in Okinawa, Japan has been charged and will be tried by a US military court, Manila's foreign affairs department announced in a statement on Friday.

"On July 28, the United States Army charged Specialist Ronald Edward Hopstock Jr. with the rape of a Filipino woman under section 120 of the US Uniform Code of Military Justice," the foreign affairs department said in a statement released to reporters.
