Six people have been arrested in Italy on charges of plotting to attack world leaders at a G8 summit this summer. At least two are suspected of links with the Red Brigades, a terrorist organisation which kidnapped and assassinated prominent political figures in Italy in the 1970s and ’80s.Originally scheduled to take place in Sardinia, the G8 conference will now be held in central Italy. “A few months ago, when the G8 conference was still scheduled on the Sardinian island of Maddalena, we intercepted calls about a plot. The plans were not for an outright attack but to bypass the security system,” said anti-terrorism police chief Lamberto Giannini. Another 15 people are under investigation following the crackdown – the outcome of a two-year-long operation against the so-called New Red Brigades. Several of the suspects are believed to have links with the group’s former leader Desdemonda Lioce, arrested in 2003 and serving life in prison on terrorism charges.
