Two New York men were arrested in a sting after police witnessed them trying to buy guns and grenades. Algerian-born Ahmed Ferhani, 26, and Moroccan-born Mohammed Mamdouh, 20, bought three pistols, ammunition and an inert grenade after a seven-month sting. At a news conference, New York Police commissioner Ray Kelley said "Farhani also expressed interest in bombing the "Empire State Building." The plot unraveled Wednesday. It was the 13th planned attack by Islamist militants on New York City since the Sept. 11, 2001, attacks.
