Pillow fighters take over Hong Kong for Pillow Fight Day
Pyjama-clad combatants have taken to the streets of Hong Kong with their pillows for International Pillow Fight Day.
They joined "fighters" in more than 100 cities around the world for the event's sixth year.
Many see the flashmob as a fun way to relieve the stress and pressure of city life.
