An unnamed informant alerted security officials of the plan; six cell-members have already been questioned.
Cell members had reportedly planned to bribe an airport employee into aiding them in perpetrating the attack, to have taken place during the world football championships in the city in the summer of 2007.
From Ynet News:
An El Al spokeswoman in Israel said the company does not respond to reports about security matters.
Members of the terror cell are "mostly" from Jordan, originating in "Palestine." The other members are also from Arab countries. They all lived in the German states Rheinland-Pfalz and Hessen. The police searched nine residences.
