NEW YORK, Sept. 14 (UPI) -- Security officials in New York City met for hours Monday in an effort to provide a level of unprecedented protection for Pope Francis's 38-hour visit and the United Nations General Assembly, both slated for next week.
The New York City Police Department and other security officials and administrators held a tabletop exercise Monday in Manhattan to work through security procedures and worst-case scenarios that could arise during the pontiff's visit on Sept. 24.
"Have people ready for every occasion," New York City Mayor Bill de Blasio, who sat in on the exercise, said. "[The NYPD] is doing a lot."
Federal agencies, like the U.S. Secret Service, are involved in the security preparations, and the effort is being prepared by the Department of Homeland Security. The Secret Service will be the lead agency for security.
Authorities cycled through various scenarios Monday to develop necessary responses and envisioned different circumstances that called for a number of potential actions.
Officials from numerous federal and local agencies attended Monday's exercise, including the FBI, the Fire Department of New York, the Metropolitan Transportation Authority, U.S. Coast Guard, Federal Emergency Management Agency, U.S. Department of Justice, Customs and Border Protection and U.S. Department of State.
"We have an explosion ... It's an [improved explosive device] explosion from a backpack. So we've got to get everyone involved. There's no report of casualties yet," NYPD Lt. John Mahon said in running through a hypothetical scenario during the exercise, The New York Times reported Monday.
Pope Francis arrives Sept. 22 in Washington, D.C., before traveling to New York, and Philadelphia on Sept. 26. He will return to Rome on the evening of Sept. 28.
Adding to the city's security responsibility, the UN General Assembly -- including nearly 200 foreign dignitaries -- will also be held next week to coincide with the pope's visit.
More than 80,000 tickets to see the pope in New York have been issued via random lottery selection. Monday, the NYPD said every ticketholder must be accompanied by valid photo identification. Anyone not possessing such ID will be turned away as part of the heightened security effort.
