French authorities have started transporting migrant children out of Calais to processing centres around France, amid tensions around the closure of the vast Jungle camp.
Three buses carried a group of unaccompanied boys, mainly teenagers, out of the camp on Wednesday morning.
French authorities transferred more than 5,000 adult migrants out of Calais last week, but the fate of its 1,500 unaccompanied children remained unclear.
Migrants from the Middle East and Africa converged on the Jungle in hopes of crossing the English Channel to Britain.
President Francois Hollande said this week that the children would be transferred within days to "dedicated centres" where British officials can explore whether they have the right to UK asylum.
Mr Hollande said the others would be put in the care of French child welfare services.
