WAKEFIELD, Mass. —

Eleven men are in custody after a police standoff with heavily armed men who claimed to not recognize laws.

The men were clad in tactical, military-style gear with long guns and pistols, Massachusetts State Police Col. Christopher Mason said. They claimed they were going to Maine for "training."

The standoff shut down part of I-95 in Wakefield in both directions, prompting heavy traffic as people hit the road for the Fourth of July weekend.

The standoff began around two a.m. when police noticed two cars pulled over on I-95 with hazard lights on, authorities said at a Saturday press briefing. Police stopped to assist them.

The men refused to put down their weapons or comply with authorities' orders, claiming to be from a group “that does not recognize our laws," police said. They took off into a wooded area, where two men have been arrested.

The standoff shut down part of I-95 in Wakefield in both directions, prompting heavy traffic as people hit the road for the Fourth of July weekend.

In Massachusetts, Interstate 95 runs from the Rhode Island line, around Boston to the New Hampshire line. Wakefield is just east of where Interstate 95 and 93 meet north of Boston.

Residents in Wakefield and nearby Reading were advised to lock their doors and shelter in place.

Wakefield police said in its statement that no threats had been made but the men were considered armed and dangerous.
