U.S. Northern Command on Saturday directed increased security measures at all military installations in its area of responsibility, which includes the continental United States and Alaska.

The directive is based on world events and USNORTHCOM is not aware of any specific threats to installations, a command press release said.

The command said employees and visitors to military installations in its area of responsibility should expect elevated security measures and increased wait times.

The release did not say how long Increased Force Protection Condition (FPCON) measures would be in place. Installation commanders are tasked with enforcing FPCON measures and have authority to declare an increased FPCON level.

The directive comes as protests are expected across the United States and as the U.S. Army holds a birthday parade in the nation’s capital. Anticipation of potential unrest has prompted some states to activate their National Guard forces. It also comes as the U.S. helped Israel counter an Iranian missile barrage.

NORTHCOM’s release did not name either potential domestic unrest or potential foreign threats as a cause for increased FPCON.

Early Saturday a Minnesota state lawmaker and her husband were shot and killed and another state lawmaker and spouse were shot in what Gov. Tim Walz called a targeted attack. Walz said his Department of Public Safety is recommending people not attend political rallies in the state until a suspect is apprehended. It remains unclear if there is a connection between the shootings and the protests.

U.S. Indo-Pacific Command similarly raised its FPCON to Bravo on Friday, June 13, and implemented additional Charlie-level measures.
