FBI Director Robert S. Mueller met with Austrian officials Thursday to discuss last week's arrests in Vienna of two suspected al-Qaida operatives and assess the threat of terrorism during next summer's Euro 2008 soccer tournament.
Interior Minister Guenther Platter described the meeting as an "intensive exchange of ideas" on counterterrorism efforts in Austria, which will co-host the June 7-29 tournament along with Switzerland.
Vienna police last week arrested three people suspected of ties to a video posted on-line in March that threatened Austria and Germany with attacks if they do not withdraw military personnel from Afghanistan.
All three were Austrian citizens of Arab origin in their 20s. One of the suspects later was released for lack of evidence. Canadian authorities have arrested a fourth suspect believed linked to the video threat.
