Prince Harry began his three-day tour of Estonia and Italy on Friday, arriving in the Baltic country's capital Tallinn for his first engagement.
The Prince laid a wreath at the monument to the War of Independence in Freedom Square, known as Vabaduse väljak, before attending a reception at the Estonian Parliament with government officials.
Prior to the reception, however, Harry delighted waiting fans, chatting to them and posing for selfies. The 29-year-old even obliged when one supporter asked him to hold the crown-shaped sign she had brought bearing his name for a photo.

Harry later met with veterans who will take part in the Invictus Games, the international sporting event for wounded, injured and sick service personnel that Harry launched in March.

The 29-year-old will then journey to Italy for the first time since a family holiday to the Mediterranean country in 1985, to attend a number of events commemorating the Allied Campaign in Italy during WWII.
On 18 May, Harry will start the day at the Polish commemoration service ceremony where he will lay a wreath on behalf of the Queen.
The Prince will then visit the Abbey of Monte Cassino - an original sixth-century monastery which was destroyed during the battles of 1944 - where he will meet wounded Italian veterans, some of whom will be taking part in the Invictus Games.
