PORT-AU-PRINCE, Haiti (AP) — Here are key findings on AP's investigation into in the U.N.'s peacekeeping crisis:

1. The AP reviewed 12 years of UN data on sexual misconduct and exploitation, and found an estimated 2,000 allegations against peacekeepers and personnel — signaling the crisis is much larger than previously known.

2. More than 300 of the allegations involved children, AP found, but only a fraction of the alleged perpetrators served jail time.

3. A U.N. investigation report from 2007 obtained by AP shows that 134 Sri Lankan peacekeepers sexually exploited and abused at least nine Haitian children. No one was jailed, and Sri Lanka kept participating in U.N. missions in Haiti and elsewhere.

4. Sri Lanka refuses to specify what happened in the investigations into the soldiers who were disciplined for the child sex ring in Haiti and why so few were punished given that the U.N. internal report cited 134 soldiers.

5. In the latest U.N. annual report, Sri Lanka is cited for its "best practices" involving a paternity payment made recently to a Haitian woman. It took Sri Lanka nearly a decade to make the payment.
