CNN —The World Cup match between Portugal and Uruguay was briefly interrupted by a pitch invader waving a rainbow flag on the field at the Lusail Iconic Stadium on Monday. A pitch invader runs onto the pitch wearing a t-shirt with a message saying: 'Respect for Iranian Woman' on the back and holding a rainbow flag. Molly Darlington/ReutersThe participation of Iran, who play the US Men’s National Team on Tuesday in a Group B match, in the World Cup has been played out against the backdrop of the country’s domestic turmoil. Meanwhile the issue of LGBTQ+ rights in Qatar has also been a constant theme at the World Cup. The victory means that Portugal has advanced to the next stage of the World Cup with a game to spare whereas Uruguay needs a victory from its final game against Ghana to have any hopes of progressing.
