Every evening since 1959, the security forces of India and Pakistan have performed a joint military ceremony at the Attari-Wagah border. Soldiers from both sides perform elaborate and highly choreographed maneuvers, including high leg raises, before the border gates are opened and the two flags are lowered simultaneously as the sun sets. The flags are folded, two soldiers shake hands, and the gates close again. For the spectators, the ceremony is a symbol of both the cooperation and the rivalry that exist between the two nations.
