Greenlanders have celebrated National Day, the Arctic island's biggest summer festival, to mark the solstice with songs, cannon salutes and dances under 24 hours of sunlight.

Locals in traditional clothing made of pearl collars and seal hides started the day by marching toward the Colonial Harbour with Greenland’s national flags.
