In a statement May 28, Jesuit Father Federico Lombardi, Vatican spokesman, said the massacre was "a motive of great sorrow and concern for the Holy Father and the entire Catholic community, as it is for the international community which has expressed unanimous condemnation of the incident."
"Renewing its appeal for an end to all forms of violence, the Holy See exhorts the parties involved and the entire international community to spare no efforts to resolve this crisis through dialogue and reconciliation," Father Lombardi said.
The Vatican also said religious leaders and those who believe in God "are called to commit themselves to promoting the peace which is so much sought after, for the good of the whole population."
The United Nations estimates that about 9,000 civilians have died since the uprising against President Bashar al-Assad's government began in March 2011.
