The Nation Signed with the Blood of the Cross
Italy and Vatican on guard after ISIL threat
From the article:
The Italian government is on high alert after threats from the Islamic State called Italy “the nation signed with the blood of the cross.” And the country would probably need help to confront the militant group.
Italy is one of a handful of major Western counties that has not been victim of a large-scale terror assault since the Sept. 11 attacks in the USA. The Vatican — the de facto seat of worldwide Christianity — is in Rome, so the city could be a target.
