A Swiss newspaper has been told by police that the tournament is a target cited by al-Qaeda.
"A flurry of messages have been monitored, by police and security officials in Switzerland, on two Islamist internet forums – sos minbar and As-Sahab – which are favoured by the extremist terrorist group as a means to awaken dormant cells," says a story in the Daily Mirror.
The paper talks of messages calling on "fighters of the faith". One is reported to say, "Let’s transform these two countries, the safest in Europe, into hell – like the hell in Iraq or Afghanistan." Another says, "The hour has come for fighters of the faith. They must make themselves heard."
