FRANKFURT: Police in the western German state of Hesse mounted raids in six cities on Tuesday against suspected Islamic extremists accused of raising money to carry out terrorist attacks. "We have information that Islamic extremists engaged in petty crime are building a network and the logistics for terrorism," police spokesman Peter Liebeck said.Searches in the neighbourhood surrounding the main train station in the business capital Frankfurt turned up evidence of drug violations, illegal immigration and passport counterfeiting, he said. More than 100 armed officers sealed off a street and stormed Turkish and Arab businesses. Liebeck said authorities believed that the extremists were using local snack shops and call centres as fronts. Police also searched homes and offices in the cities of Kassel, Dillenburg, Wetzlar, Marburg and Bad Vilbel.
