Pope Francis called for national reconciliation in the US on Wednesday, saying that while racism is intolerable, the street violence that has broken out is “self-destructive and self-defeating”.

Francis broke his silence on the tensions in the US, which has seen eight nights of protests over the death of a black man in police custody, by dedicating the entire English-language section of his weekly audience to the turmoil there.

He called the death of George Floyd, a 46-year-old African-American who died after a white policeman pinned his neck under a knee for nearly nine minutes, “tragic”.

Francis said he was praying for all who died as a result of the “sin of racism”, including Floyd.

“My friends, we cannot tolerate or turn a blind eye to racism and exclusion in any form and yet claim to defend the sacredness of every human life,” Francis said.

“At the same time, we have to recognise that the violence of recent nights is self-destructive and self-defeating. Nothing is gained by violence and so much is lost,” he said.

Francis asked Americans to implore God for “the national reconciliation and peace”.

President Trump came under fire from Christian leaders who criticised him for using religious symbols as a backdrop for staged photo opportunities.
