Security officials are carrying out operations at highway toll booths and in stations to control the potential arrival of protesters from outside Rome as part of increasingly stringent measures around the area of Piazzale Ostiense in the Italian capital where a number of groups could defy a ban issued by the central police department and stage a pro-Palestinian demonstration, security sources said Thursday. The alert level is high to prevent potentially violent groups from infiltrating the event with security officials monitoring the social media pages of anarchic and university groups, the sources said. In particular, security measures for Saturday will be put in place Friday at a meeting chaired by new Rome police commissioner Roberto Massucci. Source: Ansa News Agency
