On Tuesday afternoon, another unusual incident reportedly occurred aboard a plane landing in Portugal.

This time, the incident was on a Ryanair plane departing from London Stansted, England, and involved two passengers who were involved in a brawl after the plane touched down on the runway at Lisbon's Humberto Delgado Airport.

According to SIC Notícias, which broke the news and released a video of the incident, police were called to the plane at 6:45 p.m. due to the conflict.

Because of the altercation, all passengers were stuck on the plane for about an hour.

It is currently unknown whether anyone was arrested or identified.

According to the television channel, it all started during the flight, when a child began crying. However, tempers only flared when the plane landed in Lisbon and headed toward the apron.

In the footage released, several men can be seen standing up in the aisle. It is clear that there is, or was, a conflict. One of the passengers even puts his hands to his head. A child can also be heard crying and the mother trying to calm him down. "We're fine now," the woman says to her child.
