Pope Francis criticized European countries' response to migrants and asylum seekers during his visit to a refugee camp on the Greek island of Lesbos Sunday.

Why it matters: The pope said "migration is a humanitarian crisis that concerns everyone," but little had changed in the global response to displaced peoples since his first visit to Lesbos five years ago, per a transcript of his remarks. "Human lives, real people, are at stake. ... let us stop this shipwreck of civilization!"

• His comments come less than two weeks after 27 people died when their U.K.-bound inflatable boat sank in the English Channel between France and the United Kingdom — sparking a dispute between the British and French governments on how to respond to such crossings.

What else he's saying: Francis noted that Greece, like other countries, continued to be hard-pressed. "[I]n Europe there are those who persist in treating the problem as a matter that does not concern them," he added. "This is tragic."

• The pope said it's "distressing" to learn of proposals to build walls and barbed wire as a solution for displaced peoples seeking help.
• "We are in the age of walls and barbed wire," he added. "To be sure, we can appreciate people's fears and insecurities, the difficulties and dangers involved, and the general sense of fatigue and frustration, exacerbated by the economic and pandemic crises."
