Three suspected Islamic extremists have been arrested in Italy sparking fresh fears that the nation could be the target of a terrorist attack. Judicial sources said the trio, all Algerians, were believed to be “potentially operative” and ready to carry out a strike. A government source however is maintaining that no attack was planned in Italy.Two men were arrested in the northern city of Brescia. A third suspect was picked up at Naples in the south. Police believe all three had been in contact with a cell from Algeria’s Salafist movement, the main armed Islamic organisation in the north African country. The group has been accused of having links to al-Qaeda. A close ally of the United States, Italy has deployed troops in Iraq. It has received numerous Internet threats purporting to be from Islamic militants who have vowed to strike against Italian interest.
