New York, Boston and other cities in the United States bolstered security on Friday night after deadly gun and bomb attacks on civilians in Paris, but law enforcement officials said the beefed-up police presence was precautionary rather than a response to any specific threats.
There were no specific or credible threats of an attack on the United States of the type that occurred in Paris on Friday, U.S. Department of Homeland Security Secretary Jeh Johnson said.
Johnson said in a statement that the FBI and DHS are closely monitoring the situation after more than 100 people were killed in a series of attacks in Paris, and the agencies are in contact with their counterparts in the region.
