Mexico City officials set the Guinness World Record for the world's largest serving of sandwiches arranged in a continuous line, unveiling a giant torta stretching 100 metres (328 feet) and weighing more than 1.5 metric tonnes.

The record-breaking row of sandwiches was assembled during Torta Fair, an annual food festival celebrating one of Mexico's most popular street foods.
