Naval Base Guam's main gate off Route 1 Marine Corps Drive was closed and a line of cars were backed up outside as no one was allowed access following a bomb threat the Navy received at 12:15 Wednesday afternoon.

Those living and working on the southern military installation were forced to shelter in place.

This message alert even sent to them stating the security forces were the ones who got the call and that officials were securing the Coast Guard buildings and multiple barracks following the threat.

An explosive ordnance disposal team and other emergency responders were activated to both locations to assess the threat.

By 2:30 Wednesday afternoon, the Navy posted on social media that information for pick up of students at the base's elementary and middle schools would be announced after the all clear was given.

About half an hour later, the Navy announced the all clear, lifting the shelter in place, and reopening the main gate and back gate of the base.

Still, Naval Base employees and residents were asked to remain clear of the buildings and nearby areas as authorities continue to investigate.
