Vandals in Sweden have burned down for the 27th time a giant straw goat meant to symbolise Christmas spirit.

The 13-metre high and 3.6-tonne heavy straw goat was engulfed in flames early on Saturday after unidentified assailants attacked it in the Swedish town of Gavle, 150km north of Stockholm.

The straw goat is a centuries-old Scandinavian yule symbol that preceded Santa Claus as the bringer of gifts.

Since 1966, when the tradition of erecting the giant straw goat in the town square was introduced, Vandals have burnt it down 27 times.
