Primary school children from across Wales have joined First Minister Carwyn Jones to unveil personal messages for world leaders about their hopes for the future.
Thirty messages written by nine and 10-year-olds onto postcards have been picked to be given to each of the Nato world leaders - including Prime Minister David Cameron, US President Barack Obama and French President Francois Hollande - during the summit.
The postcards answer the question, what would you like to have changed in the world by the time you are adults?
Mr Jones said the messages - which will be on tables at the summit dinner - were heartfelt and could make an impression.
