VATICAN CITY - Pope Benedict made an emotional appeal for an end to violence and massacres in Iraq, as he recalled during Palm Sunday services the death of a kidnapped Chaldean Catholic archbishop.

The half-buried body of Paulos Faraj Rahho, the archbishop of the northern Iraqi city of Mosul was found on Thursday, two weeks after he was snatched by gunmen from his car.

"His beautiful testimony of faith to Christ, the Church and his people that he did not want to abandon despite numerous threats, pushes me to raise a strong and sorrowful cry: enough with the massacres, enough with the violence, enough with hatred in Iraq!" he said.

Speaking to thousands of pilgrims clutching palm fronds and olive branches -- symbols of peace -- in St. Peter's Square, the Pope called on Iraqis to "raise their heads" and rebuild their nation with reconciliation, forgiveness and justice.
