Britain is marking Queen Elizabeth II’s 91st birthday with gun salutes, as the monarch celebrates quietly at home.
A troop of the Royal Horse Artillery rode horse-and-gun carriages past Buckingham Palace before staging a 41-gun salute in Hyde Park at noon local time.
There was also a 62-gun salute at the Tower of London an hour later.
The queen is Britain’s oldest and longest-reigning monarch, having become queen on February 6, 1952.
She is also the world’s longest-reigning living monarch since the death of Thailand’s King Bhumibol Adulyadej last year.
The queen usually spends her birthday privately.
She also has an official birthday, marked in June — when the weather is better — with the “Trooping the Colour” military parade.
