Following an outbreak of violence across Paris Friday evening, Philadelphia police said it was alerting officers to make extra checks on specific locations around the city.
In a statement, Lt. John Stanford urged the public to be extra vigilant and to "notify us if they see any suspicious activity occuring in our City."
Stanford said the department had not received and credible threats to the city. "we will also increase our presence at sporting events this weekend just to ensure that we are visible to all and ensuring safety."
Meanwhile, Gov. Tom Wolf said in a statement that there were no "credible or increased threats" to Pennsylvanians but that "Pennsylvania State Police and Office of Homeland Security are in communication with the FBI and other federal agencies regarding the attacks in Paris and are continuing to monitor the situation for any changes."
At least 127 people were killed in the worst attacks on France since World War II. Americans were among the 200 wounded, the State Department said on Saturday. Eight attackers targeted at least six locations in the French capital, authorities said. Police said they killed one of the terrorists and the others blew themselves up.
French President Francois Hollande vowed a "merciless" response against the perpetrators, as ISIS claimed responsibility.
