German authorities say they disrupted a massive attack on an American military base. They arrested three suspected Islamic militants who are also suspected of targeting the airport at Frankfurt. A German prosecutor says these three suspects trained at terror camps in Pakistan. They allegedly had obtained more than 1,500 pounds of hydrogen peroxide — a substance that can become a powerful explosive. A German lawmaker says authorities feared that the attack could have come in the next few days, as we approach the anniversary of the September 11, 2001 attacks.
