KABUL, Afghanistan — An unpublished United Nations report on female police officers in Afghanistan found accounts of pervasive sexual violence and harassment by their male colleagues, according to Afghan and Western officials familiar with the report.

The report, which the United Nations has circulated only among senior Afghan officials at the Interior Ministry, found that about 90 percent of the policewomen interviewed described sexual harassment and sexual violence as a serious problem, and that about 70 percent of the policewomen said that they had personally experienced sexual harassment or sexual violence themselves, according to people who saw the report or had it described to them.

While a much smaller fraction reported either being raped or otherwise sexually assaulted, the overall picture was of a police force in which women were constantly at risk.

Although the report has not been made public and was not made available to The New York Times, two other recent reports touched on similar problems, though they did not focus as closely on the issue of sexual assault and harassment.
