In the wake of the deadly explosions at an airport and subway station in Brussels, some United States cities are seeing an increase in police presence, particularly Washington, D.C., Los Angeles and New York.
ABC News reports that U.S. officials say there is “no specific threat to the United States that we know.” The attacks on Brussels killed at least 34 people.
ISIS has claimed responsibility for the attacks.
What concerns U.S. officials is the prospect of a coy-cat attack. ABC News senior justice correspondent Pierre Thomas said on Tuesday that the FBI has been monitoring around 100 people with 24-hour surveillance that they feel could be inspired by the attacks on Brussels.
Amtrak says it has deployed extra officers in the wake of the attack. “We have reminded Amtrak employees to look for and report any suspicious activity and unattended items and reissued guidance pertaining to facility inspections and active shooter incidents,” the company said in a statement.
