Fiat G.91 in Combat?

While broswing through the questions section on aerospaceweb.org I found an article where someone asked what type of an aircraft they had seen and they provided a picture. The aircraft in the picture is a G.91. After the author of the site answered the question about what type of aircraft it was, they provided a brief history of the G.91. In that write-up it is mentioned that Portuguese G.91’s saw combat. I’ve never heard this. Can anyone provide any information?

Here’s the link to the question and answer where I read all of this.
