Federal authorities have warned local law enforcement officials across the country about a heightened concern involving possible terror attacks targeting the July 4th holiday.

There was no specific or credible threat of attack. The intelligence bulletin prepared by DHS and the FBI. 

The bulletins are frequently issued in advance of major U.S. holidays out of an abundance of caution and concern that operatives may exploit the timing to generate greater attention, reported USA Today. 

In a statement, DHS Secretary Jeh Johnson said local law enforcement was being encouraged to be "vigilant and prepared'' in preparation for July 4th celebrations.

"We will also adjust security measures, seen and unseen, as necessary to protect the American people,'' Johnson said. "We continue to encourage all Americans to attend public events and celebrate this country during this summer season, but always remain vigilant.''
