A two-minute silence has been observed across the UK to recollected the nation’s war dead for Armistice Day.
Prince Harry has laid a wreath at the National Memorial Arboretum in Staffordshire for the commemorations.
Silence fell at 11:00 GMT to remember servicemen and women killed in battle.
England and Scotland footballers are expected to risk transgressing Fifa rules forbidding “political statements” when they wear poppy armbands at their World Cup qualifying match at Wembley later.
People gathered at war monuments and in schools, offices and other public places across the UK to pause for two minutes to commemorate the moment the firearms fell silent for peace at the end of World War One, on 11 November 1918.
Hundreds of people attended the Royal British Legion’s Silence in the Square event in Trafalgar Square, where poppies were laid in the fountains and music was performed by a range of artists including Russell Watson.
A service of remembrance was also held at the Cenotaph, where vocalist Cerys Matthews read the poem In Memoriam by Ewart Alan Mackintosh.

The sun shone and as 11 o’clock approached, Trafalgar Square filled with people of all ages.
They listened to moving lyrics and songs and as the The Last Post began at one minute to 11:00 GMT, all traffic was stopped and one of London’s busiest squares fell silent.
The Royal British Legion which organised this event has called for a “rethinking” of Remembrance, asking people to think not just of those who died in the two world wars but more recent conflicts as well.
After a bugler signalled the end of the two minutes’ silence, the traffic restarted and hundreds of poppy petals were scattered into Trafalgar Square’s fountains representing those who sacrificed themselves for others in conflict.
In Bristol, 19,240 shrouded figures were laid out on College Green, each one representing a soldier who was killed on the first day of the Battle of the Somme.
Prince Harry read Rupert Brooke’s poem The Soldier, written at the beginning of the war, as part of the service at the National Memorial Arboretum.
The Prince of Wales has attended a service in Bahrain, where he laid a wreath and met senior military representatives and UK veterans working in the Middle East.
The Royal British Legion charity has organised dozens of events for Friday following weeks of fundraising by selling poppies.
Armistice Day is followed by Remembrance Sunday on 13 November, when royals and senior politicians pay their respects at the Cenotaph memorial in London.
Meanwhile, the Football Associations of England and Scotland have said they will let players wear black armbands with poppy emblems despite a warn from Fifa, football’s governing body, that doing so could violate regulations banning “political, religious or commercial” messages.
However, Fifa has since issued a statement saying it has not banned England and Scotland players from wearing armbands featuring the poppy as has been reported, because it cannot pre-judge what symbols would constitute such a breach.
Both FAs have said they are willing to face any penalty – though they insist it will not be submitted to that.
