“A small makeshift bomb has exploded in a street in central Rome, causing slight damage to a building belonging to a French religious establishment and three parked cars, police said. There was no immediate word on what was behind the explosion early on Friday morning, which occurred hours before a visit to Pope Francis by French president François Hollande, but security was tight near the Vatican before the meeting.”
