In the largest case of harassment at a single US military installation in two decades, training instructors at San Antonio's Lackland Air Force Base have been accused of molesting or harassing 31 female trainees in the past three years.

The allegations, charging dozens of male military training instructors, MTIs, with harassing, molesting or raping the female trainees, has prompted the Pentagon to order an investigation.

Leon Panetta, the US Defence Secretary, has called for "strict discipline to make sure sexual assault doesn't happen".
