From a refugee camp on the Greek island of Lesbos, Pope Francis decried European indifference to the plight of migrants in the Mediterranean as a "shipwreck of civilization.”

“The Mediterranean, which for millennia has brought different peoples and distant lands together, is now becoming a grim cemetery without tombstones. This great basin of water, the cradle of so many civilizations, now looks like a mirror of death,” Pope Francis said in Lesbos on Dec. 5.

“Let us not let our sea be transformed into a desolate sea of death. Let us not allow this place of encounter to become a theatre of conflict. … Please, brothers and sisters, let us stop this shipwreck of civilization,” he said.
