BARACK Obama has wished the teams competing in the Invictus Games well as Prince Harry staged a party to welcome those taking part in the sporting spectacle.

The American President recorded a video message of support for the wounded servicemen and women who have been chosen to represent their nations in the Paralympics-style championships.

On the eve of the Games' opening ceremony, which will be staged tomorrow night in London, Prince Harry also thanked the athletes, many with missing limbs or other serious injuries, for enthusiastically embracing the concept.

Rockers The Foo Fighters rattled the windows of the US ambassador's official residence, Winfield House in Regent's Park, as they entertained hundreds of guests at the party held in the building's sprawling garden.

The President said in his pre-recorded message played to the crowds who included the teams, their families and supporters: "I know it's going to be a fiercely competitive few days but the truth is that everyone of you in these games, every service member and veteran, has already earned our highest admiration and our deepest gratitude.

"When your countries asked you to serve, to risk everything to protect our safety and our freedom, you and your families answered the call and just as you inspire us with your courage on the battlefield, your grit and resilience when you take the playing field, your incomparable souls inspire us today."
