A pillow fight involving hundreds of people has taken place in London.

Armed with pillows and an appetite for rambunctious weekend activity, participants gathered in Kennington Park to mark International Pillow Fight Day 2017.

On the strike of 2pm, the battle commenced. Pillows were swung, feathers flew, and allegiances were made across the park.

The event, which is celebrated in cities across the world, is in its 8th year.

“It’s beautiful. And it’s international, and everyone’s enjoying themselves,” said one participant.

Another commented: “We thought it was going to be an April Fools thing, but it turns out everyone is actually here. It’s amazing.”

It might sound like a recipe for a weekend trip to A&E, but the rules are made clear at the beginning: be gentle with one another.

Pillow fighters of every age attended the free event with many wearing fancy dress, as suggested on the event’s Facebook page.

Similar gatherings took place across the globe including events in Amsterdam, Vancouver and Rio De Janeiro.
