Turin, May 8 - A driver was injured by a group of hooded attackers late Tuesday evening as he was leaving a work site for the controversial high-speed TAV rail line near the Piedmont city of Turin. Police said that the group began pummelling the man's truck as he was leaving the Maddalena construction site where he works as a driver for Martina Service. The high-speed rail line will eventually connect Turin to Lyon. Some critics of the rail link, which Italy and France say they will begin building in 2014, have staged violent protests denouncing its high cost and claiming it will cause environmental damage. The driver, who suffered light injuries to his hand, was released from the hospital shortly after being treated. "This is a vile act of intimidation, using violence to instill a climate of terror," a company spokesman said.
