English: Among the contradictions in the accounts that have been given, there has also been an attempt to reassure international public opinion over Mr Babitsky' s fate, by confirming the theory that there was an exchange of prisoners with Chechen fighters which, inter alia, if this did actually take place, would constitute a breach of international law, which certainly does not provide for the involvement of civilians in such circumstances.
Spanish:A la vista de la contradictoriedad de las versiones facilitadas, se ha tratado de tranquilizar a la opinion publica respecto a la suerte de Babitski acreditando la tesis de un intercambio de prisioneros por combatientes chechenos que, entre otras cosas, si se hubiera producido realmente, constituiria una violacion del Derecho internacional que no preve la implicacion de civiles en estas circunstancias.
