ISIS is calling for attacks on uniformed personnel, causing security upgrades in Los Angeles, its airports and throughout Southern California, US officials told NBC News on Friday.
ISIS has called on its sympathizers to attack Western Interests around the world, according to NBC.
Los Angeles was already using two-man patrols, but the increased security measures extended to Los Angeles International Airport this week, according to officials.
There haven’t been any specific terror plots discovered, but officials fear that individual sympathizers may act alone to target uniformed personnel or specific locations, according to sources that spoke under the condition of anonymity.
FBI Director Jim Comey has said investigations into suspected ISIS sympathizers are under way in all 50 states.
According to NBC News, a Department of Homeland Security spokesman would not comment on what specific intelligence has caused increased concerns along the West Coast. But, he added, officials had boosted security in recent months.
“Over the last few months, we have made a number of security adjustments, including enhanced screening at select overseas airports and increasing random searches of passengers and carry-on luggage on flights inbound to the U.S., reflecting an evolving threat picture,” the spokesman said.
