Prince Harry visited NATO soldiers in Estonia and observed joint military exercises on the second day of his trip to the Baltic nation.
Dressed in army fatigues, Harry gave awards for outstanding service to Estonian soldiers who had completed tours in Afghanistan.
Estonian servicemen have been based with British troops in the military base Camp Bastion in Afghanistan's Helmand province, where Prince Harry also served.
The military exercises observed by the Prince are taking place about 100 kilometres from Estonia's south-eastern border with Russia. Around 600 NATO troops are taking part, with some 100 soldiers from Britain.
Earlier this week, Britain offered to deploy more fighter jets in the Baltic states to reassure its NATO allies in the face of tension between Russia and the West over Ukraine.
