PHILADELPHIA INTERNATIONAL AIRPORT (WPVI) -- This is just a drill.
That's what the Philadelphia Police Department wants anyone around Philadelphia International Airport Tuesday night to know.
The airport is hosting Philadelphia police, along with several other law enforcement agencies, to conduct a training exercise.
The training will last for several hours, but officials say it will not interfere with airport operations in any manner.
Police say the public should not be alarmed if they see a larger than normal police presence at the airport.
Announcements pertaining to this training exercise will be repeated often at the airport as well as placed on the visual paging monitors until the exercise is complete, police say.
