Prince Harry visits the Tomb of the Unknowns at Arlington National Cemetery.
Britain's Prince Harry continues his seven-day U.S. tour in Washington today, where he's focusing on the fallen and wounded soldiers.
At Arlington National Cemetary Prince Harry, in his Royal Air Force uniform, paid his respects to Americans who died in the war on terror then laid another wreath at the Tomb of the Unknowns.
The visit had a more solemn tone than his thursday visit to Capitol Hill.
Tourists were screaming, giggling and snapping pictures so loudly security had to quiet them.
Even Capitol Hill staffers couldn't resist getting a glimpse of the prince as he toured an exhibit on landmines, one of his mother's favorite causes.
