The following comes from a December 2 Catholic News Agency article:

Four alleged terrorist sympathizers who made internet threats against Pope Francis have been arrested. While Italian authorities described them as “highly dangerous,” they said they did not appear to be involved in any specific plot.

“They were threatening the Pope, celebrating the recent attacks in Paris and threatening the former U.S. ambassador to Kosovo,” said Carmine Esposito, a police chief in the northern Italian city of Brescia.

Their online threats included claims that Francis will be the last Pope.

Police said that the alleged terrorist team was a “highly dangerous group” that “propagated the ideology of jihad through social networks.” The team allegedly has links to jihadists in Syria.
