Explosion Hits Military Recruiting Station at New York's Times Square
....""If it is something that's directed toward American troops than it's something that's taken very seriously and is pretty unfortunate," said Army Capt. Charlie Jaquillard, who is the commander of Army recruiting in Manhattan."...
He said no one was inside the station, where the Marines, Air Force and Navy also recruit.
Witnesses staying at a Marriott hotel four blocks away said they could feel the building shake with the blast.
"I was up on the 44th floor and I could feel it. It was a big bang," said Darla Peck, 25, of Portland, Oregon.
"It shook the building. I thought it could have been thunder, but I looked down and there was a massive plume of smoke so I knew it was an explosion," said Terry Leighton, 48, of London, who was staying on the 21st floor of the Marriot."....
