A report released by a Colombian human rights commission reports that U.S. troops and contractors in the South American country have sexually assaulted 54 underage Colombian children. The U.S. military said it will investigate the allegations but also refuted some of the charges.

Between 2003 and 2007 U.S. troops and contractors have allegedly raped 54 children, and the perpetrators have not been charged, having been removed from the country before prosecution, according to Colombia Reports. The Colombian-based news site cites an 800-page independent report on the conflict between the Colombian government and FARC forces.

In a section of the "Historical Commission for the Conflict and Its Victims" Renan Vega of the Pedagogic University in Bogota explains the role American troops have played in the country and claims some are culpable of sexual crimes.

"There exists abundant information about the sexual violence, in absolute impunity thanks to the bilateral agreements and the diplomatic immunity of United States officials," he wrote, adding that multiple underage girls were raped by U.S. troops at a military base near the town of Melgar "who moreover filmed [the abuse] and sold the films as pornographic material."

Speaking with the Daily Beast, Army spokesperson Cynthia O. Smith said the Army was taking the allegations seriously and would investigate.

"The U.S. Army Criminal Investigation Command is currently coordinating with Colombian authorities and plans on conducting criminal investigations into credible allegations of sexual assault or criminal acts committed by U.S. soldiers while in that country," she said. "We take this issue very seriously and will aggressively pursue all credible allegations."

However, Colombians have been waiting for years, in many cases, for American troops to be tried for their alleged crimes. Vega, who wrote the allegations, told TeleSur that the reason they have not been tried is due to an agreement between Colombia and the U.S.

"There is abundant information about the sexual violence, which occurred under absolute impunity because of the bilateral agreements and the diplomatic immunity of United States officials," he said.

One of the most widely reported cases is that of a 12-year-old girl raped by an American officer and a contractor back in 2007. El Tiempo reports the girl's mother has been fighting to have those involved charged, but the men, identified as Sgt. Michael Coen and contractor Cesar Ruiz, were taken out of the country.

The U.S. refutes this allegation, saying it has investigated and had sent a CID investigator to question the family. The mother told El Tiempo, a man named Jhon Ramirez told her that he was there to resolve the problem and asked her to sign a paper in English. She claims the paper she refused to sign would absolve the U.S. military from paying damages.

In a statement to the Daily Beast, however, CID chief of public affairs Christopher Grey said the attack allegations were unfounded and explained the encounter with the CID officer did not go as told.

"That agent is fluent in Spanish. Again, I am not confirming any identities to protect the rights of all involved. The agent was there to obtain a witness statement in order to fully investigate the allegations. Everything he presented to the woman was in Spanish," Grey explained.

"After interviewing her, he asked her to sign her statement. This was in no way a 'waiver' of any type. Additionally, the agent was not armed at the time of the interview. We strongly reject any claims that this was anything but a very professionally conducted witness interview concerning the allegations."
