Europeans who have joined fellow insurgents fighting in Iraq could use their newly acquired skills to launch terror attacks at home, Europe's anti-terror coordinator warned Thursday. Gijs de Vries said EU security forces were monitoring "the few" suspected Islamic militants leaving from the continent for Iraq. "We do not know how many of these people will survive. We do not know how many will return," he told reporters in Jakarta, Indonesia. "Some of them may return with skills that could prove extremely dangerous to the European people." Analysts have expressed concern for some time that Iraq has replaced Afghanistan as a global training ground for terrorists. Many of the terrorists responsible for the wave of bombings in Indonesia in recent years either fought in Afghanistan or attended terror training camps there in the 1990s.
