The footage features Donald Trump Jr., the US president's son, who has been in Venice in recent months.
The video, titled "Duck hunting in Venice - Italian Job Teaser", was uploaded to YouTube a month ago. An extended version has been shared on other social platforms, where Trump Jr. is seen aiming and shooting at the ducks.
The scene of the hunt, identified by local residents, appears to be the Pierimpič Valley, located in Campagna Lupia.
