Britain’s Queen Elizabeth, the world’s oldest and longest-reigning monarch, celebrated her 91st birthday in a usual low-key fashion on Friday.

Artillery gun salutes in London’s Hyde Park and at the Tower of London will mark the occasion although the queen, who normally spends her birthday privately, has no formal engagements planned herself.
