A delegate of the International Committee, Mr. Jacques de Heller took part in the exchange of prisoners between Algeria and Morocco during the night of 14/15 April at Oujda on the frontier between the two countries. This concerned military personnel captured during the frontier conflict in the autumn of 1963. The exchange was assisted by the Moroccan and Algerian Red Crescent Societies. As usual, the ICRC had visited the prisoners whilst in detention and had distributed a certain amount of material relief.
