About 2 percent of Roman Catholic clerics are sexual abusers, an Italian newspaper on Sunday quoted Pope Francis as saying, adding that the pontiff considered the crime "a leprosy in our house."

But the Vatican issued a statement saying some parts of a long article in the left-leaning La Repubblica were not accurate, including one that quoted the pope as saying there were cardinals among the abusers.

The article was a reconstruction of an hour-long conversation between the pope and the newspaper's founder, Eugenio Scalfari, an atheist who has written about several past encounters with the pope.
