France has moved more than 1,600 unaccompanied child refugees from the demolished "Jungle" refugee camp in Calais, as a feud with Britain dragged on over who takes care of the youths.

According to local officials, 1,616 children, mainly teenagers who had been living in shipping containers after the camp was razed late last month, had been transferred to processing centres across France on Wednesday.

More than 5,000 refugees had been transferred from Calais last week, but the fate of the children had remained unclear until Wednesday.
