South Korean lawmakers are pushing for reforms to reduce the military's judicial power after a female soldier who had suffered sexual abuse killed herself, rekindling criticism of the military's handling of sex crimes.

An air force master sergeant, identified by her surname Lee, took her life last month after being molested by a colleague. Her family said she had reported the case and sought help, but the air force only tried to cover up the assault and bully and silence her.

Air force chief Lee Seong-yong resigned last week, taking responsibility for Lee's death. The air force and defense ministry have declined to comment on the details of the case, citing an investigation, while her male colleague faces prosecution in a military court.
