In New York City, two men who federal authorities say were inspired by the Islamic State brought powerful homemade bombs to a far-right protest outside the mayoral mansion.
In Michigan, a naturalized citizen from Lebanon rammed his vehicle into a synagogue, where he was shot at by security before he shot himself to death.
In Virginia, a man previously imprisoned on a terrorism conviction was heard yelling “Allahu akbar” before opening fire in a university classroom in an attack that officials said ended when the shooter was killed by students.
The three acts of violence in the last week have laid bare a heightened terrorism threat unfolding against the backdrop of the U.S. war with Iran and as the country’s counterterrorism system is strained by the departures of experienced national security professionals at the FBI and Justice Department. The firings and resignations, along with the diversion of resources and personnel over the last year to meet other Trump administration priorities, have fueled concerns about the capability to head off a potential surge in threats.
“So much experience has been decimated from the ranks,” said Frank Montoya, a retired senior FBI official. “The folks that were best positioned to get to the bottom of it before something really bad happened” are in many cases no longer with the government, he said, meaning less experienced personnel assigned to the threat are “starting from way behind.”
