Fribourg, Switzerland - Calls by Al-Qaeda extremists to attack Switzerland and Austria during Euro 2008 are being taken seriously by authorities, a senior Swiss security official said.
Messages on "sos minbar" and "As-Sahab", two internet sites favoured by the terrorist group and calling for attacks on the two host nations, had multiplied in recent weeks, the official was quoted as saying by La Liberte daily published Thursday.
"We are taking these threats seriously," he said.
