"One of humanity's greatest conquests has been, precisely, the overcoming of racism," Benedict told pilgrims and tourists at his summer residence in Castel Gandolfo, near Rome.

"Unfortunately, however, in several countries new, worrisome displays" of racism are manifesting themselves, the pontiff said.

Benedict said that while racism is "often tied to social and economic problems", those factors "can never justify contempt or racial discrimination".

The pope didn't cite any country by name.

Instead, he urged Christians to help society "overcome any temptation to resort to racism, intolerance and exclusion" toward foreigners.

Some Italian church figures have added their voices to a debate over the current crackdown by Italy's conservative government on crime by foreigners.

Polls in Italy indicate that many Italians blame crime on immigrants.
