Mayor Michael Nutter told reporters Monday evening that officials have extended hours and tours of duty for personnel and are "monitoring actively a variety of key and historic locations" and would deploy resources as needed.
"For the moment our focus is that something has happened in one of our cities, so every American city will have a response," Nutter said.
He also said security will be stepped up for the annual Broad Street Run scheduled for Sunday, May 5.
"Runners and spectators will see a more visible security presence on race day," said Nutter.
The mayor, flanked by the police commissioner and other city officials, said residents would be able to see some of the measures taken, but they won't be able to see others.
"We will be beefing up security, no question about that," Philadelphia Police Commissioner Charles Ramsey said.
Ramsey says a security plan was certainly already in place for the upcoming Broad Street Run, but those plans will now be reassessed after today's explosions in Boston.
Ramsey admits that having a strong security presence along the route of a race or a parade can be daunting and that's why he is asking the people of Philadelphia to be vigilant and not just during public events.
"People have to help in this. If you see something, say something. You got to pay attention to what's going on and if it looks strange, it probably is," Ramsey said.
Nutter says it's also important to realize that as of tonight no specific threats have been made against the City of Philadelphia.
So, for now, city officials are urging everyone to go about your business as usual and keep the people of Boston in your thoughts and prayers.
All while the local law enforcement operates under a heightened level of security.
"We certainly are having radio quips sent out to our police officers to remind them of the need to be very vigilant," Ramsey said.
Anyone who sees something suspicious should call 911, 311 or 215-686-TIPS (8477)
