Gun salutes to mark Queen's 88th birthday
The Queen's 88th birthday has been marked across the UK with traditional gun salutes.
A 41-gun royal salute was fired in Green Park in London and a 62 gun-salute from the Tower of London.
Gunners from 105th Regiment Royal Artillery fired two 21-gun royal salutes at Edinburgh and Stirling Castles.
Salutes were also fired in Northern Ireland and Wales. The Queen is spending the day privately at Windsor.
The Queen was born on 21 April 1926 at the home of her mother's parents in Mayfair.
However, her birthday is also celebrated officially each year in June at the Trooping the Colour service - which this year will take place on 14 June.
The gun salute at Green Park was carried out by the King's Troop Royal Horse Artillery using 13-pounder World War One guns drawn by 71 horses.
Before the King's Troop arrived, the Band of the Honourable Artillery Company and Royal Yeomanry played celebratory music.
The 62-shot salute at the Tower of London was completed by the Honourable Artillery Company.
It included 21 shots for the Queen's birthday, 20 because it is a royal palace, and 21 to follow a tradition in which ships would fire their guns before entering the City of London to show they were not threatening.
Gunners from 105th Regiment Royal Artillery fired two 21-gun royal salutes in Scotland; while in Wales, the salute was fired at Cardiff City Hall.
The salute in Northern Ireland was carried out at Hillsborough Castle in County Down.
