NEW YORK, N.Y.- Investigators are trying to find out who set off a small bomb early today outside a military recruiting station in New York's Times Square.
The explosion caused minor damage and no injuries, but it prompted a huge police response that disrupted travel through and beneath Times Square.
The blast shattered a window in front of an Uncle Sam recruiting poster.
The center is normally staffed by two noncommissioned officers but was empty at the time.
The facility has been the occasional focus of antiwar protests. And the commander of Army recruiting operations in Manhattan says if the blast was directed toward American troops, then, in his words, "It's something that's taken very seriously and is pretty unfortunate."
Guests at a nearby hotel say they heard a "big bang" and could feel the building shake.
