President Juan Manuel Santos has said he will donate almost $1m in Nobel peace prize money to the victims of Colombia’s half-century conflict.



Santos made the announcement Sunday during a visit with his family and top government officials to an impoverished town in western Colombia where dozens of people were killed while sheltering in a church during an intense battle between leftist rebels and far-right militias.



He promised the residents of Bojayá that he would not give up on securing peace with the Revolutionary Armed Forces of Colombia (Farc) despite voters’ rejection of a deal with the guerrillas in a referendum a week ago. More than 96% of residents of Bojaya voted for the peace deal.



“You symbolize the suffering of the victims of 52 years of war and are at the center of the solution to this conflict,” a visibly moved Santos told the crowd. “The victims have taught me that the capacity to forgive can overcome hatred and rancor.”



Of the 81 Colombian municipalities hardest-hit by the conflict, 67 voted for the peace deal, according to the Bogotá-based Peace and Reconciliation Foundation.

Santos was awarded the Nobel peace prize on Friday less than a week after the peace accord was shot down in a vote that even surprised government opponents.



Polls taken before the referendum showed the “yes” vote winning by an almost two-to-one margin after Santos and Farc leader Timochenko signed the 297-page accord in front of world leaders six days earlier.



During his visit to Bojayá, Santos attended a mass at the church rebuilt following the mortar attack launched by Farc. Residents gave him a replica of the Christ statue mutilated during the attack, a gift the president said he valued as much as the Nobel prize and which encouraged him to find a way to implement the peace accord.



“I’m not going to falter a single minute. I’m not going to give up a single second” in the search for peace, he said.



Santos said the donated money would be channelled to infrastructure projects in conflict areas and to victims’ groups.



Farc leaders have twice visited Bojayá to ask forgiveness and discuss with community leaders actions to help the town rebuild.



The Nobel peace prize carries an $8m kronor ($930,000) award. A ceremony will take place 10 December in Oslo, Norway.
