New York - Seven years after the September 11 terrorist strikes, New Yorkers on Thursday will remember the attacks that killed more than 2,700 people with the destruction of the World Trade Center's twin towers.
The city will observe the anniversary with renewed calls for vigilance against the constant threats of new terrorist attacks. Names of the dead will be read yet again.
The presidential nominees of both US major parties, Republic Senator John McCain and his rival, Democratic Senator Barack Obama, plan to attend ceremonies at Ground Zero, site of the destroyed towers.
