Harry Styles has been hit in the eye by an object thrown at him while on stage for a concert in Vienna.
Video on social media shows the 'Watermelon Sugar' singer wincing in pain and having to recover after being struck.
It's reported the incident happened after the first song of his encore and the footage shows Styles bending half over and clutching his face.
Many took to social media to voice their anger at what is being perceived as a growing trend of artists being struck by various thrown items.
"They gonna make artists not want to perform anymore. At this point it's getting scary... like why can't people just perform without being attacked?" one asked on Twitter.
"Why would anyone do this to him? Sad to watch," another asked.
"People have to stop this!" someone else commented.
It's not the first time Styles has been struck with items thrown by audience members while performing.
In November 2022 he was hit by thrown Skittles while he was on stage in Los Angeles. He was videoed at the time seemingly having trouble opening one eye.
Styles was also pelted with chicken nuggets on stage in New York in August last year, and hit by bunches of flowers in Cardiff in Wales.
It's the latest in a series of recent attacks on singers while they've been performing on stage.
Last week, footage emerged of someone hurling a cellphone at Drake while in Chicago during the opening night of his It's All A Blur tour. It hit him on the wrist before landing on the stage.
In June, Bebe Rexha had to be taken to hospital with a cut and bruised face after being hit with a thrown phone in New York City. Footage shows the stunned singer grasping her face and falling to her knees, and the event was cut short as she was escorted off-stage.
Pink has also been targeted with a fan at London's Hyde Park throwing up their mother's ashes on stage in a clear plastic bag.
Adele has angrily spoken out about the harm artists face from throwing crowd members.
While on stage for her Las Vegas residency, she asked her audience if they had noticed people appear to be "forgetting f**king show etiquette at the moment".
"I f**king dare you, dare you to throw something at me," she joked at the time. "Stop throwing things at the artist!"
