First responders who were called to the World Trade Center site in the days and weeks following 9/11 will be on the outside looking in at next month’s anniversary ceremony.

Organizers say police officers, firefighters and rescue workers will not be invited to take part in the primary 10th anniversary ceremony activities.

Instead, they will be asked back at the site another day for a separate ceremony.

Officials cite security and a lack of room as the reasoning behind the decision.

In addition to President Barack Obama and former President George W. Bush, thousands of family members will also be on hand.

It’s estimated as many as 91,000 people took part in the initial search and rescue at the World Trader Center site.
