In Kabul, a military chaplain prepares for a service in a British cemetery to mark Remembrance Day.
Commonwealth countries as well as other countries around the world observe two minutes of silence at the eleventh hour on the eleventh day of the eleventh month (11:00 am, 11 November), marking the time (in the United Kingdom) the Germans signed the Armistice which ended World War I in 1918.
