Shetland celebrates midwinter Viking fire festival
Horned warriors are massing in Shetland for the annual Up Helly Aa fire festival.
A thousand men will parade through the streets before burning a replica Viking ship. The event is derived from the ancient feast of Yule, in which the Vikings celebrated the rebirth of the sun. Shetland, which lies 100 miles north of the north of the Scottish mainland, was colonised by the Vikings in the eighth century and only became part of Scotland in 1469.
