Prince Charles and the Duchess of Cornwall are meeting around 100 Jewish refugees who escaped to Britain as children from Nazi Germany.

Some 10,000 Jewish children were brought to the UK between 1938 and 1939 - on the brink of World War II - under the "Kindertransport" plan.
The royal couple are hosting a reception for a group of the former child refugees at Clarence House.
It is part of a week of events marking the 60th anniversary of the war's end.
This week has been nominated Veterans Awareness Week as it falls midway between VE Day and VJ Day.
On Monday, Prince Charles opened a "living museum" in London's St James's Park.
Visitors will learn about experiences of the wartime generation - such as air raids, black-outs and code breaking.
The former Kindertransport children, now in their 60s and 70s, are also involved in the museum.
Buckingham Palace was lit on Monday with images of World War II - including flights of German bombers and civilians sheltering underground from their raids.
The images will be shown every night until Saturday.
The Royal Mail is also celebrating Veterans Awareness Week on Tuesday by issuing a new first-class stamp showing St Paul's Cathedral during the Blitz.
Sunday has been nominated National Commemoration Day.
At the end of that day, with the Queen standing on Buckingham Palace's balcony, a WWII-era Lancaster bomber will drop a million poppies onto The Mall in memory of war dead.
