A passenger waiting for his luggage to be checked-in, stands beside a sign with the security advice inside the main terminal of airport September 5, 2007. Germany said on Wednesday it had foiled a plan by Islamist militants to carry out "massive bomb attacks" against U.S. installations and arrested the three men behind it. Federal prosecutor Monika Harms could not confirm reports the accused, two German nationals and one Turk, had been targeting Frankfurt international airport and a major U.S. military base in Ramstein. But she said they had been seen scouting out U.S. installations such as discos, pubs and airports. REUTERS/Kai Pfaffenbach (GERMANY)
