For the effects of a public apology to the survivors of the events of the Ituango massacres and the next of kin of the victims, the Court appreciates the partial acknowledgement of international responsibility made by the State during the public hearing held on September 23, 2005, in this case.

Since some of the inhabitants of La Granja and El Aro lost their homes as a result of the facts of this case (supra para. 125(81)), the Court considers that the State must implement a housing program to provide appropriate housing280 to the surviving victims who lost their homes and who need this. The State must implement this program within five years of notification of this judgment. f) Plaque 408. In addition, the State must erect a plaque in an appropriate public place in La Granja and in El Aro, so that the new generations are aware of the events that took place in this case.
