SOFIA.- A dancer, known as "Kukeri", performs on January 30, 2015 during the International Festival of the Masquerade Games in Pernik near the capital Sofia. The three-day festival, which started on January 29, has participants sporting multi-colored masks, covered with beads, ribbons and woolen tassels while the main dancer, ladened with bells to drive away sickness and evil spirits, sways like a wheat spikelet heavy with grain.
