Thousands honour fallen troops
Thousands of people throughout the UK have gathered to honour British troops who've died while fighting for their country in past and current conflicts.
The Queen led the tributes at London's Cenotaph, joined by Princes William and Harry and Prime Minister Gordon Brown.
Veterans then took part in a military march past the Cenotaph as crowds lined the streets to pay their respects.
This year, Remembrance Sunday is three days before the 91st anniversary of the end of the First World War.
But Remembrance isn't just about the World Wars.
Serving soldiers in Afghanistan held their own Remembrance Sunday service
It's also about remembering all the people who have died while fighting for their country since then, including the recent conflicts in Afghanistan and Iraq.
British troops at Camp Bastion in Afghanistan also held a service to remember their fallen comrades.
In Scotland, First Minister Alex Salmond gave a reading at Edinburgh's St Giles Cathedral, and lay a wreath at the Stone of Remembrance.
More than 60 wreaths were laid during a commemoration ceremony at Belfast's City Hall.
And in Wales, the Army's last-surviving all-brass band, the Regimental Band of the Royal welsh, led the national Remembrance Sunday parade in Cardiff.
