September 11, is the tragic day when 19 militants hijacked four airliners and carried out suicide attacks against targets in the United States. Two of the planes were flown into the towers of the World Trade Center in New York City, a third plane hit the Pentagon just outside Washington, D.C., and the fourth plane crashed in a field in Pennsylvania.
NEW YORK: Until a few months ago, the part of New York City where crowds will gather on Thursday morning to mark the 13th anniversary of the Sept. 11 attacks on the United States had been mostly fenced off to the public.
