Prince Harry says the Invictus Games are about supporting the individuals taking part and not the war.
Some 400 wounded service personnel from 13 countries are taking part in the Games, an international sporting event for wounded, injured and sick Servicemen and women.
Harry has championed the Games with the Duke and Duchess of Cambridge also supporting them.
Prince Harry has said he feels 'young at heart' ahead of turning 30 on September 15.
Speaking after presenting medals at the Invictus Games, he said: 'I'm slowly starting to feel old. I think 30 is one of those first milestones when you drive through a village and see the 30mph sign. It's that constant reminder going 'I am actually quite old'.
'But I don't feel too old. I think i'm always young at heart', the Prince added.
The Prince of Wales said it was 'splendid' news that he was to become a grandfather for the second time.
During a visit to an upholstery studio in Bermondsey, south London, Charles said: 'What did i do?' when congratulated on the news about the Duchess of Cambridge's pregnancy.
He added: 'It hasn't arrived yet - (but) splendid, we're very excited'.
The Queen "will be proud" to be the monarch of an independent Scotland, according to Alex Salmond.
Scotland's First Minister also said he had an audience at Balmoral "but the proper position is you don't discuss these matters in public".
I want the Queen as head of state, as Queen of Scots of an independent Scotland as her ancestors were.
I think Her Majesty the Queen, who has seen so many events in the course of her long reign, will be proud to be Queen of Scots, and indeed we would be proud to have her as monarch of this land...
And I think the statement from the Palace about the Queen's neutrality in this matter is a perfectly satisfactory and perfectly sensible one.
A new wax model of Prince Harry has gone on display at Madame Tussauds in London to celebrate his 30th birthday.
The new figure shows the Prince in combat uniform to reflect his job as a captain in the Army Air Corps.
The figure cost £150,000 and took a team of sculptors and artists four months to create.
A mother who also suffered from the same problems in pregnancy as Kate Middleton said the extreme morning sickness she suffered left her worrying how she would survive.
Amanda Shortman told Good Morning Britain she was bedridden by hyperemesis gravidarum by the sixth week of her pregnancy and eventually lost over 10% of her pre-pregnancy weight because of the condition.
The Duchess of Cambridge could face worse sickness during her second pregnancy than her first, experts have said.
Kate is being treated by doctors at her Kensington Palace home for hyperemesis gravidarum, a rare condition which causes severe vomiting during pregnancy.
It is the same illness which led the Duchess to be treated in hospital for three nights in December 2012 while she was pregnant with Prince George.
"It's highly likely that if you have had it before you will have it again and it's generally worse in subsequent pregnancies. It starts earlier and is usually more severe," Nicola James, trustee of the charity Pregnancy Sickness Support, said.
The Duke of Cambridge said he is "thrilled" at the prospect of becoming a father for the second time.
Reflecting on "a tricky few days" for the Duchess, he said the announcement came earlier than planned due to another bad case of morning sickness.
The Queen has expressed her delight at the news - and Prince Harry said it was all very exciting.
ITV News Royal Correspondent Tim Ewart reports:
Prince William's uncle Earl Spencer has welcomed the "fantastic" news that he and wife Kate are expecting their second child.
"It is just such happy-making news," he told LBC Radio. "I have never known a period of news where things have looked so dark and bleak around the world and to have this pop up is just fantastic.
"I think that's really what it's about, it's just making the nation a happier place and that is what today's news does."
Prince Harry has joked about the news he is likely to be another step away from being King following the Duchess of Cambridge's second pregnancy.
Asked about being pushed one further down the line, the Royal laughed and said: "Great!"
