Britain's Prince Harry is to pay official visits to Estonia, Italy, Brazil and Chile in May and June, a royal spokesperson said on Friday.
In Estonia he is to thank the Defence Forces, who have had a company of soldiers under British command in Afghanistan since 2006, for their support of British troops, as well as visiting injured soldiers.
The 29-year-old younger brother of Prince William trained as an Apache helicopter pilot and served in Afghanistan, before switching to an army desk job in January. He has made helping wounded military personnel a priority, taking part in charity expeditions with injured servicemen to the North Pole in 2011, and the South Pole last year.
He also launched the Invictus Games this year, a Paralympic-style sporting event.
His Italian visit will be based around events commemorating Italy's role in World War II, in particular the 70th anniversary of the Battle of Monte Cassino, which saw some of the conflict's bloodiest fighting.
In Brazil, which Harry also visited two years ago, and Chile, he would be building on the existing relationships, the spokesperson said.
No official dates were given for the trips, but British media reported that Harry's visit to Brazil would likely coincide with the football World Cup and an England match. - Sapa-dpa
