ROME (Reuters) -A bomb exploded outside the home of one of Italy’s top investigative journalists late on Thursday, damaging two cars and a nearby house, prompting messages of solidarity for the reporter from colleagues and politicians.

Sigfrido Ranucci, who hosts RAI’s weekly “Report”, Italy’s best-known investigative journalism programme, has been for years under police protection. He said both he and his newsroom had received many threats of various kinds, including bullets.

The rudimentary device, likely made from firework explosives, was planted outside the front gate of Ranucci’s house in Campo Ascolano, about 30 kilometres (19 miles) south of Rome, the journalist told RAI state broadcaster on Friday.

He added that the explosion happened about 20 minutes after he had returned home.
