Pope Francis has criticised the Trump administrationâ€™s policy of separating migrant families at the Mexican border, saying populism is not the answer to the worldâ€™s immigration problems.
Speaking to Reuters, the Pope said he supported recent statements by US Catholic bishops who called the separation of children from their parents â€œcontrary to our Catholic valuesâ€ and â€œimmoralâ€.
â€œItâ€™s not easy, but populism is not the solution,â€ Francis said on Sunday night.
In a rare, wide-ranging interview, the pope said he was optimistic about talks that may lead to a historic agreement over the appointment of bishops in China, and said he may accept more bishopsâ€™ resignations over a sexual abuse scandal in Chile.
Reflecting at his Vatican residence on his five years as pope, he defended his leadership of the Roman Catholic Church against criticism by conservatives inside and outside the Church who say his interpretation of its teachings is too liberal.
He also said he wanted to appoint more women to top positions in the Vatican administration.
One of his most pointed messages concerned President Donald Trumpâ€™s zero-tolerance immigration policy, in which US authorities plan to criminally prosecute all immigrants caught crossing the Mexican border illegally, holding adults in jail while their children are sent to government shelters.
The policy has caused an outcry in the United States and has been condemned abroad as videos emerged of youngsters held in concrete-floored enclosures and an audio of wailing children went viral.
US Catholic bishops have joined other religious leaders in the United States in condemning the policy.
â€œI am on the side of the bishopsâ€™ conference,â€ the pope said, referring to two statements from US bishops this month.
â€œLet it be clear that in these things, I respect (the position of) the bishops conference.â€
Francisâ€™ comments add to the pressure on Trump over immigration policy. The pope heads a church which has 1.3 billion members worldwide and is the largest Christian denomination in the United States.
The president has strongly defended his administrationâ€™s actions and cast blame for the family separations on Democrats.
â€œDemocrats are the problem,â€ Trump said on Twitter on Tuesday. â€œThey donâ€™t care about crime and want illegal immigrants.â€
The US crackdown chimes with a new political mood sweeping western Europe over the large numbers of migrants and asylum-seekers, most of them escaping conflict and poverty in the Middle East and Africa.
The pope said populists were â€œcreating psychosisâ€ on the issue of immigration, even as aging societies like Europe faced â€œa great demographic winterâ€ and needed more immigrants.
Without immigration, he added, Europe â€œwill become empty.â€
