Bill O'Reilly is facing new claims that he fabricated a story about witnessing the execution of four nuns in El Salvador during the country's civil war.
The allegations came days after liberal watchdog, Media Matters for America, questioned O'Reilly's report that in 1977 he witnessed the suicide of a friend of JFK shooter Lee Harvey Oswald, and Mother Jones disputed his coverage of the Falklands War.
O'Reilly claimed he has 'seen guys gun down nuns in El Salvador' and 'was in El Salvador and I saw nuns get shot in the back of the head' while working at CBS, according to Media Matters.
The Fox News man appeared to be referencing a well-known case of four nuns executed by the Salvadoran national guard in December 1980.
Experts in the El Salvadoran conflict have said that following the tragedy, there were no church people killed in the country for more than eight years.
